Question

8⁻⁵*8⁻⁵÷8⁻⁸ !!!!!!!!!!!!!!!!!!!!!!

Answer 1

$8^{-5+(-5)-(-8)}=8^{-2}= \frac{1}{64}$

Answer 2

8⁻⁵·8⁻⁵/8⁻⁸ = 8⁽⁻⁵⁻⁵)/8⁻⁸=8⁻¹⁰:8⁻⁸=8⁻¹⁰⁻⁽⁻⁸⁾=8⁻²=1/8²=1/64

Answer 3

To simplify the expression, let's break it down step by step:

Step 1: Simplify the exponents 8^(-5) * 8^(-5) ÷ 8^(-8)

When multiplying two numbers with the same base but different exponents, you can add the exponents: 8^(-5) * 8^(-5) = 8^(-5 + -5) = 8^(-10)

Similarly, when dividing two numbers with the same base but different exponents, you can subtract the exponents: 8^(-10) ÷ 8^(-8) = 8^(-10 - -8) = 8^(-10 + 8) = 8^(-2)

Step 2: Evaluate the final expression 8^(-2) = 1 / 8^2 = 1 / 64

So, 8^(-5) * 8^(-5) ÷ 8^(-8) simplifies to 1 / 64.
