Question

what is √2 . √72 =

Answer 1

You can also do it by breaking them apart inside the square root:

 

(√2)(√72) = √2 * √2*36 = √2√2 √36 = 2*6 = 12 

 

Good luck.

Answer 2

(√a)(√b)=√ab

(√2)(√72)=√2*72=√144 which means the square root of 144; in other words what number multiplied by itself is equal to 144 ? The √ symbol means the principal or nonnegative square root.

√144=12 because 12*12=144
