$$(\sqrt[7]{x})^{21} $$
$$\sqrt[5]{x^4 * x^5 * x^6} $$

anonymous · Answer

is the second one x^15 divided by 1/5?

anonymous · Answer

Your close it is x^15 as you added the exponents together. Add you will divide but you will divide the x^15  by 5.

anonymous · Answer

how do you do that ._.

anonymous · Answer

okay

anonymous · Answer

also is it just me or is everyone that you cant see smartscores, they're just orange

loser66 · Answer

take the exponent inside * ( times) the degree outside

[(\sqrt[7]{x})^{21}\] the exponent inside is 21
the exponent outside is 1/7
times them together, you have $21*\dfrac{1}{7}=3$ so that the answer is x^3

loser66 · Answer

The smartscore is fake!! I have 99 under my name but it is fake. I am not that good.

anonymous · Answer

ok that makes sense, what about number 1 though
how do you do x^15 / 5

anonymous · Answer

i mean the second one

loser66 · Answer

$$x^4*x^5*x^6 = x ^{4+5+6}=x^{15}$$

anonymous · Answer

$$\sqrt[5]{x^4*x^5*x^6}$$ = $$x^{15}$$

anonymous · Answer

what about the 5 in front of the square root

loser66 · Answer

that is just the inside exponent (15)
outside exponent is 1/5
times them together you have $15*\dfrac{1}{5}=3$ so the answer must be x^3
