Question

What is the square root of 0.36?

Answer 1

`+-0.6`

Explanation:

Since `sqrt(36)=+-6`, we know that `6` is the square factor of `36`, and we know `sqrt(36)` will be greater in magnitude than `sqrt(0.36)`. Therefore, we can try `0.6`: `(0.6)*(0.6)=0.36`. This means `sqrt(0.36)=+-0.6`

Answer 2

`+-0.6`

Explanation:

`"note that "0.36=36/100`

`rArrsqrt0.36=+-sqrt(36/100)=+-sqrt36/sqrt100=+-6/10=+-0.6`
