Question

HELP ASAP! 98 POINTS!!

Answer 1

sqrt(50) = 5 * sqrt(2)

Explanation:

take 25 and then sqrt it.

you get 5

keep the sqrt(2) as it is irrational

so the answer in 5 * sqrt(2)

Answer 2

`√(50)=√(25\cdot2)=√(25)\cdot\sqrt2=5\sqrt2\ -\ CORRECT`



`1 < \sqrt2 < 2\ \text{because}\ 1^2=1 < 2 < 2^2=4`

`1.41^2=1.9881\\\\1.42^2=2.0164\\\\1.9881\ \text{is closer to 2}\\\\\text{therefore}\\\\√(50)=5\sqrt2\approx5\cdot1.41=7.05\approx7.1`
