MAKE SURE YOU ISOLATE THE TERM WITH X THEN USE LOG

OpenStudy (freckles):

don't think you need log

OpenStudy (anonymous):

THEN WE DO NOT, LN

OpenStudy (destinyyyy):

4x ^3/2 =12 x^3/2 = 3

OpenStudy (destinyyyy):

I have no clue what log is

OpenStudy (freckles):

raise both sides to (2/3) power

OpenStudy (anonymous):

OH i THOUGHT THAT WAS X IN THE EXPONENT HAHA MY BAD

OpenStudy (destinyyyy):

x= 3 correct?

OpenStudy (freckles):

\[x^{\frac{3}{2}}=3 \\ x^{\frac{3}{2} \cdot \frac{2}{3}}=3^{\frac{2}{3}}\]

OpenStudy (anonymous):

YOUR RATIONAL EXPONENT MAY BE REWRITTEN AS RADICALS

OpenStudy (destinyyyy):

Yeah.. Then the x is alone. And 3 *3=9 divide that by 3 = 3

OpenStudy (anonymous):

nooooo lol not like that

OpenStudy (destinyyyy):

Then what?

OpenStudy (anonymous):
