7 times the square root of 10 = the square root of 490

7sqr10 = sqr490

6sqrx = sqr36x

just square the coefficient and stick it back into the square root sign and multiply it by what's already in there.

square 7 = 49. 49x10= 490

square 6 = 36 36 times x 36x

We have a degree of 2 for square root, that is the reason 7 become 7^2 when going into the root, then we get square root of 7^2 * 1007/18/21
