Practice makes perfect
We can simplify this expression by multiplying the expressions inside the radicals and multiplying the constants, separately. asqrt(b)* csqrt(d)=a* csqrt(b* d) ⇓ 4sqrt(2)* 5sqrt(8)= 4* 5sqrt(2*8) Then we can simplify the expression by rewriting the number under the square root as the product of at least one perfect square factor.
4* 5sqrt(2* 8)
20sqrt(16)
20(4)
