Question

Could someone show me how to solve these problems step by step....
I am confused on how to fully break this down to simpliest terms

sqrt 3 * sqrt 15=

sqrt 6 * sqrt 8 =

sqrt 20 * sqrt 5 =

since both terms are sqrt , you can combine them.

sqrt 3* sqrt 15= sqrt (15*3)= sqrt 45
sqrt 6* sqrt8 = sqrt (6*8)= sqrt 48
sqrt 20* sqrt5= sqrt (20*5)= sqrt 100

Answer 1

sqrt 3 * sqrt 15= sqrt 3 *sqrt 3 * sqrt 5
= 3*sqrt5

similarly sqrt 6 * sqrt 8 = 4sqrt3


and sqrt 20 * sqrt 5 = 10
