Answer 2

To simplify the expression (2^-3)^2 * 2^5 - 12^5 ÷ 6^5, let's break it down step by step:

First, let's simplify the exponents within parentheses: (2^-3)^2 = 2^(-3 * 2) = 2^-6

Now we can rewrite the expression as: 2^-6 * 2^5 - 12^5 ÷ 6^5

Next, let's simplify the exponents separately: 2^-6 = 1/2^6 = 1/64 2^5 = 32

Now the expression becomes: (1/64) * 32 - 12^5 ÷ 6^5

Let's continue by evaluating the exponentiations: 12^5 = 248,832 6^5 = 7,776

The expression is now: (1/64) * 32 - 248,832 ÷ 7,776

Next, we perform the division: 248,832 ÷ 7,776 = 32

The expression becomes: (1/64) * 32 - 32

Finally, we simplify the multiplication and subtraction: (1/64) * 32 = 1/2 1/2 - 32 = -63.5

Therefore, the value of the expression (2^-3)^2 * 2^5 - 12^5 ÷ 6^5 is -63.5.
