Question

What is the square root of 0.000000000000000000000000000000023?

Answer 1

Well...I am not sure about where did you find this number but...I found: `1.5xx10^-16`

Explanation:

`0.000000000000000000000000000000023`
can be written as:
`230/10^34`
taking the square root you get:
`sqrt(230/10^34)=sqrt(230/((10^17)^2))=sqrt(230)/10^17=`
considering that: `15^2=225`
let us assume that `sqrt(230)~~15`
so finally you get:
`~~15/10^(17)=15xx10^-17=1.5xx10^-16`
