Exercise 44 Page 263

We can simplify this expression by multiplying the expressions inside the radicals. sqrt(a)* sqrt(b)=sqrt(a* b) ⇓ sqrt(3)* sqrt(6)= sqrt(3* 6) Then we can calculate the product and simplify it by rewriting the number under the square root as the product of at least one perfect square factor.
sqrt(3)* sqrt(6)
sqrt(3 * 6)
sqrt(18)
sqrt(9 * 2)
sqrt(9) * sqrt(2)
3 * sqrt(2)
