Question

Write mathematically square root of 121

Answer 1

Explanation:

The mathematical translation of the statement:

`√(121) = √(11 *11)`

`= \sqrt{11^(2)}`

`= (11^(2)) ^{(1)/(2) }`

The indices will cancel each other out completely:

`= 11`

OR:

`√(121) = √((-11)*(-11))`

`= \sqrt{(-11)^(2) }`

`= [(-11)^(2)] ^{(1)/(2) }`

= -11
