Question

What is the square root of the fraction 81 over 144?

Answer 1

`3/4=0.75`

Explanation:

If you have a multiplication or division inside a square root you can separate them.
`sqrt(81/144)=(sqrt81)/(sqrt144)=9/12=3/4=0.75`
Note: Only for multiplication and divisions not for sums or substractions.
`sqrt(a+b)!=sqrta+sqrtb`
Both sides are not equal!
