Exponent Math Review

What is the value of 2³×2⁴?

• 2⁶

• 2⁵

• 2⁸

• 2⁷

Answer explanation

To solve 2^3 × 2^4, use the property of exponents: a^m × a^n = a^(m+n). Here, 3 + 4 = 7, so 2^3 × 2^4 = 2^7. Thus, the correct answer is 2^7.

What is the value of (3²)³?

• 9

• 3³

• 3⁵

• 3⁶

Answer explanation

To solve (3^2)^3, use the power of a power rule: multiply the exponents. Thus, (3^2)^3 = 3^(2*3) = 3^6. Therefore, the correct answer is 3^6.

Simplify a⁶/a².

• a³

• a⁴

• a²

• a⁸

Answer explanation

To simplify a^6/a^2, subtract the exponents: 6 - 2 = 4. Thus, a^6/a^2 = a^4. The correct answer is a^4.

Which expression is equivalent to x⁴⋅x³⋅x²?

• x⁶

• x⁷

• x⁸

• x⁹

Answer explanation

To combine the expressions, add the exponents: 4 + 3 + 2 = 9. Therefore, x^4 ⋅ x^3 ⋅ x^2 = x^9, making x^9 the correct answer.
