Question

What is 15 divided by the square root of 2?

Answer 1

The problem gives us `15/sqrt2`. We need to eliminate the radical denominator. We can do so by multiplying the numerator and denominator by `sqrt2`.

`15/sqrt2 * sqrt2/sqrt2 = (15sqrt2)/2 = 7.5sqrt2`

If you need to find the specific value:

`7.5 * sqrt2 ~~ 10.6`
