Question

what is the simpliest form of the quotient
4 sgrt 810 / 4 sgrt 2

Answer 1

sqrt810=sqrt81*sqrt10=9sqrt10

so:

4sqrt810/4sqrt2
=4*9sqrt10/4sqrt2
=36sqrt10/4sqrt2
=9sqrt10/sqrt2
=9sqrt10*sqrt2/(sqrt2*sqrt2)
=9sqrt20/2
=9sqrt4*sqrt5/2
=9*2sqrt5/2
=9sqrt5

There was probably a faster way to do that...

Answer 2

that is what I got but ny answer choices are
4 sgrt 162
3 4sgrt5
5 4sgrt3
3 sgrt 5

Answer 3

They're wrong :P Also it's "sqrt" not "sgrt" btw

Answer 4

sorry wrong key

Answer 5

hahaha
