Question

Simplify completely √27y²

Answer 1

\[3 y \sqrt{3}\]

Answer 2

3|y|sqrt(3). You need the absolute value around the y.

Answer 3

\[\sqrt{9*3}*\sqrt{y^2}\]
=\[3y \sqrt{3}\]

Answer 4

i dont see the choice/

Answer 5

3\[3y \sqrt{3}\]

Answer 6

and yeah there should be an absolute value sign!

Answer 7

is it 3y power of 4√3

Answer 8

If the problem is sqrt(27y^2) then the answer equals sqrt(27)sqrt(y^2) = sqrt(9*3)|y| = 3|y|sqrt(3).

Answer 9

and sqrt(x^2) = |x| = +-x

in other words if you graph sqrt(x^2) it equals a straight line in both the positive and negative directions (like an aboslute value graph)

Answer 10

____
Simplify completely √27y²

Answer 11

Yes, then the answer you seek is 3, times absolute value of y, times square root of 3.

Answer 12

you guys are the best! :)
