Question

8^-4×8^-5-------------8^-12

Answer 1

8^(-4)•8^(-5)/8^(-12)=8^(-4-5)/8^(-12)=

8^(-9-(-12)=8³=64*8=512

Answer 2

$\frac{ {8}^{ - 4} \times {8}^{ - 5} }{ { {8}^{ - 12} }^{ } } = \frac{ {8}^{ - 9} }{ {8}^{ - 12} } = {8}^{3 } = 512$

Answer 3

To solve the expression 8^(-4) × 8^(-5), you can use the rule of exponents which states that when you multiply two numbers with the same base, you add the exponents. In this case:

8^(-4) × 8^(-5) = 8^(-4 - 5) = 8^(-9)

So, the simplified expression is 8^(-9).
