Math Problem Statement

What expression is equivalent to [(-2)4]3

Solution

The given expression is:

[(2)4]3[(-2)^4]^3

Step 1: Apply the Power of a Power Property

The power of a power property states:

(am)n=amn(a^m)^n = a^{m \cdot n}

Applying this property:

[(2)4]3=(2)4×3=(2)12[(-2)^4]^3 = (-2)^{4 \times 3} = (-2)^{12}

Step 2: Simplify the Exponentiation

Since the exponent is even, we know:

(2)12=212(-2)^{12} = 2^{12}

since raising a negative base to an even power results in a positive value.

Thus, the equivalent expression is:

2122^{12}
