Question

the expression in radical notation 81^-3/4

Answer 1

81^(-3/4) = 1/ 81^(3/4) = 1/[81^(1/4)]^3 = 1/(3^3) = 1/27

Answer 2

radical notation is\[\sqrt[4]{81^{-3}}\]

Answer 3

so is the evaluated?
I need to know how to write it in radical notation first

Answer 4

See my last post.

Answer 5

ok so then when it is evaluated the answer would be 1/27

Answer 6

yes. That is the fractional answer as evaluated. The radical notation is hard to work with so it is not a "final answer".

Answer 7

Making sense?

Answer 8

thanks!!
