Answer 3

To calculate the expression 8^3 * 16^(-0.5), we need to understand the rules of exponentiation and the properties of exponents.

Let's break it down step by step:

Step 1: Evaluate the base 8 raised to the power of 3. 8^3 = 8 * 8 * 8 = 512

Step 2: Evaluate the base 16 raised to the power of -0.5. 16^(-0.5) = 1 / sqrt(16) Since the square root of 16 is 4: 16^(-0.5) = 1 / 4 = 0.25

Step 3: Multiply the results from Step 1 and Step 2. 512 * 0.25 = 128

Therefore, 8^3 * 16^(-0.5) equals 128.
