Answer 1

\[ \large \sqrt[-0.7]{0.2} \]
?

Answer 2

yes that! i don't know what the actual number is. I need that to use in the rest of my equation.

Answer 3

\[ \large \sqrt[-0.7]{0.2}=0.2^{-0.7}=\left(\frac{1}{5}\right)^{-7/10} \]

Answer 4

\[ \large =5^{7/10} \]

Answer 5

are u sure? that part of squaring it to -.7... are you sure thats correct?

Answer 6

@helder_edwin is correct

Answer 7

wait i think i made a mistake

Answer 8

\[ \large \sqrt[-0.7]{0.2}=0.2^{-1/0.7}=0.2^{-10/7}=(1/5)^{-10/7}=5^{-10/7} \]
