OpenStudy (anonymous):

do it by ur own give a try

OpenStudy (anonymous):

ive never done it before

OpenStudy (anonymous):

ok we will get rid of the -3

OpenStudy (anonymous):

$27x^\frac{-3}{2} = \frac{27}{x^\frac{3}{2}}$

OpenStudy (anonymous):

see ^^^

OpenStudy (anonymous):

how do we get rid of the one on the right hand side

OpenStudy (anonymous):

no no i had not got rid of right hand side for explaining u

OpenStudy (anonymous):

RHS is there only

OpenStudy (anonymous):

did u understand the LHS??

OpenStudy (anonymous):

yes 3^3 equals 27

OpenStudy (anonymous):

3^2 is 9

OpenStudy (anonymous):

OpenStudy (anonymous):

ok $27=3^3 = x^\frac{3}{2}$ $x = (3^3)^\frac{2}{3}= 3^\frac{2\times3}{3} = 3^2= 9$

OpenStudy (anonymous):

no it is x = square of 3

OpenStudy (anonymous):

do we not count the 1 on the right hand side
