ganeshie8 (ganeshie8):

\(\large (256)^{\frac{3}{4}}\) \(\large (4^4)^{\frac{3}{4}}\) \(\large (4^3)\) \(64\)

OpenStudy (ammarah):

did u power it to 4 cus 4^4=256?

ganeshie8 (ganeshie8):

yes ! check it urself 4*4*4*4 = ?

OpenStudy (ammarah):

256

ganeshie8 (ganeshie8):

256 = 4*4*4*4 = 4^4

ganeshie8 (ganeshie8):

easy ok. just u need to write the inside thing 256 as useful powers of something so that u can cancel the radical exponent.

OpenStudy (ammarah):

alright can u give me another prob to solve? i have a test tomm and i need to study

ganeshie8 (ganeshie8):

simplify : \(\large 16^{\frac{1}{4}}\)

OpenStudy (ammarah):

|dw:1386913686339:dw|

ganeshie8 (ganeshie8):

yes, but u dont have to change it to radical form. simply write 16 as 2^4, and cancel the fractional exponent

OpenStudy (ammarah):

wait can u draw itout

ganeshie8 (ganeshie8):

\(\large (16)^{\frac{1}{4}} \) \(\large (2^4)^{\frac{1}{4}} \) \(2\)

OpenStudy (ammarah):

ok

ganeshie8 (ganeshie8):

il give one more problem to simplify

ganeshie8 (ganeshie8):

simplify : \(\large 32^{\frac{1}{2}}\)

OpenStudy (ammarah):

2?

ganeshie8 (ganeshie8):

try again

OpenStudy (ammarah):

idk...

ganeshie8 (ganeshie8):

\(\large (32)^{\frac{1}{2}} \) \(\large (2\times 16)^{\frac{1}{2}} \) \(\large (2\times 4^2)^{\frac{1}{2}} \) \(\large (2)^{\frac{1}{2}} \times (4^2)^{\frac{1}{2}} \) \(\large (2)^{\frac{1}{2}} \times 4\) \(\large \sqrt{2} \times 4\) \(\large 4\sqrt{2} \)

OpenStudy (ammarah):

ok how much onger r u on??? cuz if any questions conme up ill ask u

ganeshie8 (ganeshie8):

il be around :) its afternoon time here in india...

OpenStudy (ammarah):

ganeshie8 (ganeshie8):

yeah i guessed that, Amar is an indian name lol. it means 'lives forever'
