Question

What is a simpler form of the radical expression ?

Answer 1

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

Answer 2

3x^5y^2

Answer 3

That was wrong

Answer 4

is the last question y^8

Answer 5

Huh ?

Answer 6

Yea

Answer 7

It's all together though under the square root sign

Answer 8

im right the teacher is wrong

Answer 9

A. 3x^2|y^2|
B. 3|x^5|y^2
C. 9|x^25|y^4
D. 9x^25|y^4|

Answer 10

(81x^20y^8)^1/4

3x^5y^2

Reason:

81^0.25 = 3

(x^20)^1/4 = 20*1/4 = 20/4 = 5 so x^5

(y^8)^1/4 = 8/1*1/4 = 8/4 = 2 so y^2

3x^5y^2

Answer 11

A is wrong

Because it's B.
