What's a rule that could be used to simply the square of any square root of a number?

Step-by-step explanation:

The squaring function x^2 and the square root function √x are inverses of one another.  Because of this, the square of the square root of a number is the number itself:  [√x]^2; this is identical to √[ x^(1/2) ]^2 = x^(2/2) = x^1.

If we are given the square root of a number, then the number itself is the square of the given square root.

Example:  Given x with the info that x is the square root of a number, then the square of that x is x^2.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

only 10/60 isn't equivalent

hope this : )
