Question

evaluate
8^-3*8^3

Answer 1

Remember:\[x^ax^b=x^{a+b}\]

Answer 2

as @pfenn1 , says, add the exponents...

Answer 3

To use the above equation, identify by analogy what \(x\), \(a\), and \(b\) are in your equation based on the left hand side, and use the right-hand side to find the simplification. That is a rule you must memorize.

Answer 4

Your expression is \[8^{-3}*8^3\]
