Question

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??

Answer 1

look for a button on your scientific calculator labeled
Exp

enter
1.1
Exp
36
± , that key makes your exponent entry negative

÷
27 =
(you should get 4.074...x 10^-38

√
=
√
=

I got 4.4926.... x 10^-10

which is their answer.

Answer 2

why do you square root it twice?

Answer 3

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.

Answer 4

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.
