I got 4.4926.... x 10^-10
which is their answer.
I have 27x^4 = 1.1 x 10^-36
I have to figure out what X equals.
The answer is x= 4.5 x 10^-10
How do you get that for the answer??

why do you square root it twice?
we had to take the fourth root of ^(1/4)
?^(1/4)
= [ (?^(1/24) ]^(1/2)
e. g. the fourth root of 81 is 3
so take √81 to get 9
then √9 = 3
so to take the 8th root, I would take √ three times consecutively.

ok, so what if you have
4x^3 = 2.80 x 10^-9
what would x equal in this case and how would you get it?
I really appreciate ur help. As you can tell i am slightly confused. Ur explanations are helping greatly.
