Answer 1

Ответ:

Объяснение:

$\frac{2^{7} *8^{-3}}{4^{-5}} =\frac{2^{7}*2^{-9}}{2^{-10}} = 2^{7+(-9)-(-10)} =2^{8}=256$

Answer 2

Sure, let's solve the expression step by step:

1. First, let's simplify the exponents: 2^7 = 128 (since 2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128) 8^-3 = 1/8^3 = 1/512 (since 8^3 = 8 * 8 * 8 = 512) 4^-5 = 1/4^5 = 1/1024 (since 4^5 = 4 * 4 * 4 * 4 * 4 = 1024)

2. Now, let's substitute the simplified exponents back into the expression: 2^7 * 8^-3 / 4^-5 = 128 * (1/512) / (1/1024)

3. Next, let's simplify the division by multiplying by the reciprocal: 128 * (1/512) * (1024/1) = 128 * 2 = 256

So, the solution to the expression is 256.
