Question

Evaluate the expression. [(3 to the power of –5)(3 to the power of 4)] exponent of 3

Answer 1

I'm assuming this is what that looks like
`[(3 ^(-5))(3^4)] ^(3)`. We need to work inside those brackets first since the base is the same on both those expressions. The base is a 3. When we multiply like bases the rule is that we add the exponents, so what we have after that is
`(3 ^(-1))^3`. Now the rule is power to power. Multiply them.
`3 ^(-3)` is your answer if you leave the exponent as a negative,
`(1)/( 3^(3) ) = (1)/(27)` if you need it positive.
