Simplify x^2 * x^3.
x^5
x^6
x^1
x^9
When multiplying expressions with the same base, you add the exponents. Here, 2 + 3 equals 5, so x^2 * x^3 simplifies to x^5. This rule is one of the basic exponent properties. Learn more about exponent properties.
Simplify (x^5)^2.
x^7
x^25
x^10
x^3
Raising a power to another power means you multiply the exponents: 5 * 2 equals 10, so (x^5)^2 simplifies to x^10. This follows the power?of?a?power rule. Review exponent laws at Purplemath.
Simplify x^0.
1
0
x
Cannot determine
Any nonzero base raised to the zero power is defined to be 1. Therefore, x^0 = 1 for any x ? 0. This is a fundamental exponent rule. See zero exponent rule.
Simplify 2^3 * 2^2.
32
8
64
16
Using the product rule for exponents, add the exponents: 3 + 2 = 5, so 2^3 * 2^2 = 2^5, which equals 32. This combines both exponent addition and evaluation. More on exponent multiplication.
Simplify x^1.
x
1
x^0
0
Any base raised to the first power is itself. Thus x^1 = x. This is one of the basic exponent rules. See exponent basics.
Simplify (3^2)^3.
243
729
36
6561
Use the power?of?a?power rule: multiply the exponents 2 * 3 = 6, so (3^2)^3 = 3^6 = 729. This rule helps simplify nested exponents. Learn power?of?a?power.
Simplify x^3 / x^1.
x^4
x^2
x^0
x
When dividing like bases, subtract the exponents: 3 – 1 = 2, so x^3 / x^1 = x^2. This is the quotient rule for exponents. Read about quotient rule.
Simplify x^2 y^3 * x^3 y^-2.
x^5 y
x^6 y
x^5 y^5
x y
Multiply like bases by adding exponents: for x, 2 + 3 = 5; for y, 3 + (–2) = 1. The simplified result is x^5 y^1, or x^5 y. See combining exponent rules.
Simplify 9^(1/2).
3
-3
9
81
A 1/2 exponent denotes the principal (positive) square root. ?9 = 3, so 9^(1/2) = 3. Negative values are not included for the principal root. More on fractional exponents.
Simplify 16^(3/4).
8
4
2
16
Rewrite 16^(3/4) as (16^(1/4))^3. The fourth root of 16 is 2, then cubed gives 8. This uses both root and exponent multiplication rules. Fractional exponents explained.
Simplify (2x^3 y^-2)^2 / (4x y).
x^5 / y^5
x^7 / y^3
x^6 / y^4
x^5 y^5
First square the numerator: (2)^2=4, x^(3*2)=x^6, y^(–2*2)=y^(–4). Then divide by 4xy: subtract exponents (x: 6–1=5, y: –4–1=–5), giving x^5 y^(–5) or x^5/y^5. Review exponent distribution.
Simplify a^(3/2) * a^(1/2) / a^1.
a
a^2
a^(1/2)
a^3
Combine exponents by adding and subtracting: (3/2 + 1/2) – 1 = 2 – 1 = 1, so the result is a^1 or a. This uses both product and quotient rules. Exponent rules reference.
Simplify (x^(1/3))^2 * x^(2/3).
x^(4/3)
x^(2/9)
x
x^(5/3)
First apply the power?of?a?power rule: (x^(1/3))^2 = x^(2/3). Then multiply by x^(2/3): add exponents 2/3 + 2/3 = 4/3. See fractional exponent rules.
Simplify (8^(2/3))^(-1).
1/4
4
-1/4
1/2
Compute inside first: 8^(2/3) = (8^(1/3))^2 = 2^2 = 4. Then raising to –1 gives 1/4. This combines fractional exponents and negative exponent rules. Fractional & negative exponents.
Simplify ((x^(-2/3) y^(1/3)) / (x^(1/3) y^(-2/3)))^(-3/2).
x^(3/2) / y^(3/2)
y^(3/2) / x^(3/2)
(y/x)^(-3/2)
x^3 / y^3
First simplify inside: subtract exponents for x (–2/3–1/3 = –1) and add for y (1/3+2/3 = 1), giving y/x. Raising (y/x) to the –3/2 inverts and applies the exponent: (x/y)^(3/2) = x^(3/2)/y^(3/2). Advanced exponent manipulations.

Cheat Sheet

  1. Exponent Laws Overview -

    A solid grasp of the product, quotient, and power rules is essential when learning how do you simplify equations with exponents. For instance, the product rule a^m ร— a^n = a^{m+n} and the quotient rule a^m รท a^n = a^{mโˆ’n} let you combine like bases with ease. Mnemonic "add with allies, subtract for separation" helps cement these rules (source: MIT OpenCourseWare).

  2. Simplifying Terms with Exponents -

    Applying exponent laws to coefficients and variables streamlines simplifying terms with exponents. For example, 3x^2 ร— 4x^3 = 12x^5 by multiplying 3ร—4 and adding exponents 2+3. Regular practice of these exponent simplification problems from Khan Academy boosts both accuracy and speed.

  3. Simplifying Exponents in Parentheses -

    The power rule (a^m)^n = a^{mร—n} is key for simplifying exponents in parentheses. As a sample, (x^2)^3 = x^6 by multiplying 2ร—3 under one base. Think "multiply inside to outside" to lock in this rule (source: Lamar University's Paul's Online Math Notes).

  4. Zero and Negative Exponents -

    Zero and negative exponents flip your view of powers: any nonzero base a^0 = 1 and a^{โˆ’n} = 1/a^n. For example, 5^0 = 1 and 2^{โˆ’3} = 1/8 simplify tricky negative exponent problems with ease. A handy trick is "zero nets one, negatives take the reciprocal" (source: University of California, Davis Math Department).

  5. Fractional Exponents and Roots -

    Fractional exponents bridge exponents and roots: a^{1/n} = โˆš[n] and a^{m/n} = (โˆš[n])^m. For instance, 8^{2/3} = (ยณโˆš8)^2 = 2^2 = 4, simplifying an exponential expression with roots. Use "root then raise, or vice versa" to recall the steps (source: Wolfram MathWorld).
