## anonymous 4 years ago Last problem Simplify: 2^3square root x^4 multiplied by ^3 square root 125x^7 I kinda know how to do this now, but the exponents totally lost me

1. anonymous

i got 40x^9 square root of 5x

2. ash2326

is this your question? $2^3 \sqrt{x^4} \sqrt[3]{125x^7}$

Yepp

I just don't know how to make the square root sign.

5. ash2326

ok now $\sqrt{x^4}= x^2$ $\sqrt[3]{125x^6*x}=5x^2\sqrt[3]x$ so we get $8*5*x^4\sqrt[3]{x}$
