Transcript text: Simplify the following expression.
\[
-2(64)^{2 / 3}
\]
What is the value of $-2(64)^{2 / 3}$ ?
Solution
Solution Steps
To simplify the expression \(-2(64)^{2/3}\), we need to evaluate the exponent first. The expression \(64^{2/3}\) can be interpreted as taking the cube root of 64 and then squaring the result. After finding this value, multiply it by -2 to get the final result.
Step 1: Calculate the Cube Root
We start by calculating the cube root of \(64\):
\[
\sqrt[3]{64} = 4
\]
Step 2: Square the Result
Next, we square the result from Step 1:
\[
4^2 = 16
\]
Step 3: Multiply by -2
Finally, we multiply the squared value by \(-2\):
\[
-2 \times 16 = -32
\]
