\[-5\sqrt[4]{1875}-\sqrt[4]{48} \over -4\sqrt[4]{1024}\]
OpenStudy (anonymous):
\[\sqrt[4]{1875}=?\]\[\sqrt[4]{48} = ?\]can you simplify these? for example \[\sqrt[4]{1024}=\sqrt[4]{2^{10}}=4\sqrt[4]{4}\]
OpenStudy (anonymous):
that one is right
48 = 2 * 2 * 2 * 2 * 3
\[\sqrt[4]{2^4 \times 3} = ?\]
OpenStudy (anonymous):
you got it yet? o.o
OpenStudy (anonymous):
\[for \space \sqrt[4]{1875}=\sqrt[4]{5^4 \times 3}=5\sqrt[4]{3}\]\[\sqrt[4]{48}=\sqrt[4]{2^4 \times 3}=?\]

if that's the answer for the numerator then you are right, don't forget the [4]
OpenStudy (anonymous):
\[\sqrt[4]{1024} = \sqrt[4]{2^{10}}=?\]
OpenStudy (anonymous):
\[-5\sqrt[4]{1875}-\sqrt[4]{48}=-25\sqrt[4]{3}-2\sqrt[4]{3}=-27\sqrt[4]{3}\]
OpenStudy (anonymous):
\[\sqrt[4]{1024}=\sqrt[4]{4 \times 4 \times 4 \times 4 \times 4}=?\sqrt[4]{?}\]
OpenStudy (anonymous):
\[\sqrt[4]{4^5}\]so you take 4 "4s" out of 5\[\sqrt[4]{4^4\times4}\]\[4\sqrt[4]{4}\space or \space 4\sqrt{2}\]

woops forgot a minus sign for the one below
OpenStudy (anonymous):
yea you can get rid of both minus sign and that's all lol
