guess, i bet you are right

to cancel out square you have to take square root both sides $\huge\rm \sqrt{m^2} = \pm { m}$

@Nnesha. So B

@Michele_Laino

7. Michele_Laino

hint: take the square root of both sides of your equation

8. nuccioreggie

C?

$$\color{blue}{\text{Originally Posted by}}$$ @nuccioreggie @Nnesha. So B $$\color{blue}{\text{End of Quote}}$$ you got that right we can factor 60 sqrt{4 times 15}= 2sqrt{15} but for this question B is right :-)

hint: we have to take the square root of 60 please keep in mind that we have two values, one positive and the other one negative, since the index of the root is an even number

Ooooh ok so it is B
