the equation looks like this \[16^{3/4}\]
OpenStudy (paki):
hmm
OpenStudy (paki):
then take (2)^4*3/4.... now cancel the 4 and you will be left with (2)^3... and take 2*2*2...
OpenStudy (paki):
clear now...?

OpenStudy (paki):
take square on both sides... it will cancel the root... and then solve for "x"...
OpenStudy (anonymous):
So it's just \[2x-1=3\]
OpenStudy (paki):
no... 2x-1=9... now solve for "x"...
OpenStudy (anonymous):
x=5?
OpenStudy (paki):
yup
