Answer 3

the expression \[\sqrt{200}\] is equivalent to

Answer 4

200/25 = 8

8 * 25 = 200

so sqrt(200) = sqrt(8 * 25) = sqrt( 8 *5^2) = 5*sqrt(8) = 5 * sqrt(4*2)

5*sqrt(4*2) = 5*sqrt(2^2*2) = 2*5*sqrt(2) = 10*sqrt(2)

Answer 5

thank you tomo

Answer 6

also

sqrt(200) = sqrt(2*100) = sqrt(2*10^2) = 10*sqrt(2)

Answer 7

yes it is right
