Answer 3

\[\Large \sqrt[4]{81x^{20} y^8}\]

Answer 4

start by writing everything in terms of powers of 4 \[\Large \sqrt[4]{3^4 (x^{5})^4 (y^2)^4}\]

Answer 5

\(\huge\ 3\sqrt[4]{x^{20}y^8}\)

Answer 6

C is ur answer my dear

Answer 7

She wants to actually learn, not be given answers @Muzzack

Answer 8

Yeah lol

Answer 9

sorry sire

Answer 10

ill leave this to you @agent0smith im terrible sorry

Answer 11

Hahahahaa its okay cx

Answer 12

Okay so now what?

Answer 13

\[\Large \sqrt[4]{3^4 (x^{5})^4 (y^2)^4}\]now you can simplify... just like a square root cancels out a square, a 4th root cancels out a power of 4.

Answer 14

Oh okay so 3(x)(y^2) ?

Answer 15

Or is that so wrong ?

Answer 16

Close but not quite. The only things that cancel are powers of 4

Answer 17

Oh so its (x^5) right ?

Answer 18

Just write the whole expression as you did a minute ago

Answer 19

Oh okay ummm 3(x^5)(y^2)?
