Exercise 22 Page 248

Consider the Product Property of Square Roots.

7sqrt(5)

Practice makes perfect

We can simplify the expression by rewriting the number under the square root as the product of at least one perfect square factor.

sqrt(245)

SplitIntoFactors

Split into factors

sqrt(49* 5)

sqrt(a* b)=sqrt(a)*sqrt(b)

sqrt(49)* sqrt(5)

Calculate root
