what is a and b?

Answer 1

use ln(a^b) = b ln(a)

Answer 2

ok do i need to take out of the 4root?

Answer 3

\[\sqrt{x} = x^{1/2}\]

Answer 4

yes you need to have an expression that look like Aln(B)

Answer 5

but since its to the 4 root would it be 13^1/4?

Answer 6

yep that's it

Answer 7

so a =1/4
b= 13

Answer 8

yes

Answer 9

to the 1/3?

Answer 10

i subtracted 1 from 1/4

Answer 15

1/4-1

Answer 16

1/4*ln 13^1/3 = 1/4 *1/3 * ln 13 = (1/12) *ln 13

Answer 17
