Power of a Power Property

Apply the power of a power property in Grade 10 algebra: (aᵐ)ⁿ = aᵐⁿ to simplify expressions with nested exponents by multiplying the exponents together.

Key Concepts

$$(a^m)^n = a^{mn}$$.

Simplify $(x^3)^4$: A power raised to another power means you multiply the exponents: $(x^3)^4 = x^{3 \cdot 4} = x^{12}$. Solve $x^{\frac{1}{4}} = 3$: Raise both sides to the 4th power: $(x^{\frac{1}{4}})^4 = 3^4$, so $x^{\frac{1}{4} \cdot 4} = 81$, which means $x = 81$.

When a power is raised to another power, you get to multiply the exponents. Think of it as a power up for your exponent! This rule is super useful for simplifying complex expressions and is the secret weapon for solving equations where the variable is trapped in an exponent. Just raise it to the reciprocal power and watch it simplify!

Common Questions

What is the power of a power property?

(aᵐ)ⁿ = aᵐⁿ. Multiply the exponents. For example, (x³)⁴ = x¹² and (2²)³ = 2⁶ = 64.

How do you simplify (x²y³)⁴ using the power of a power property?

Apply to each factor: x²⁴·y³⁴ = x⁸y¹².

How do you simplify (3x²)³?

Raise each factor to the 3rd power: 3³·(x²)³ = 27·x⁶ = 27x⁶.
