Simplify: $(a) (6 \sqrt{11}) (5 \sqrt{11}) (b) {(5 \sqrt{8})}^{2}$

Short Answer

Expert verified

Part $(a) 330$

Part $(b) 200$

Step by step solution

Part (a) Step 1. Given information.

The given square root is $(6 \sqrt{11}) (5 \sqrt{11})$ .

Part (a) Step 2. Simplify the given root.

$(6 \sqrt{11}) (5 \sqrt{11}) = 6 路鈥� 5 路鈥� 11 = 330$

Part (b) Step 1. Given information.

The given square root is ${(5 \sqrt{8})}^{2}$ .

Part (b) Step 2. Simplify the given root.

${(5 \sqrt{8})}^{2} = 5^{2} {(\sqrt{8})}^{2} = 25 {(\sqrt{8})}^{2} = 25 {(2 \sqrt{2})}^{2} = 25 路鈥� 2^{2} {(\sqrt{2})}^{2} = 25 路鈥� 4 {(\sqrt{2})}^{2} = 25 路鈥� 8 = 200$
