## anonymous 5 years ago simplify sq root of 40 and 200

1. anonymous

Square root of 40 is 2 root 10 and square root of 200 is 10 root 2

2. anonymous

does "and" mean add, multiply or are they two different problems?

3. anonymous

6.324 and 14.14

4. anonymous

i assume when it says "simplify" it means to write in simplest radical form. in which case lagrange has it

5. anonymous

$\sqrt{20}=\sqrt{4\times 10}=\sqrt{4}\times \sqrt{10}=2\sqrt{10}$

6. anonymous

it probably does not mean give a decimal approximation

7. anonymous

my mistake..sorry

8. anonymous

likewise $\sqrt{200}=\sqrt{100\times 2}=\sqrt{100}\times \sqrt{2}=10\sqrt{2}$

$\sqrt{40}= \sqrt{2 x 2 x 2 x 5} = 2 \sqrt{10}$ $\sqrt{200}= \sqrt{2x2x2x5x5}$
