In using radicals, square roots, and powers;
when trying to figure the square root of a number with a radical such as;
Now in figuring out the from the square root I know that 64 is 8, but the is does this mean that in order to get 4 we subtract 4 from 8? Meaning that for figuring out the square root of 64 is basically division(multiplication) but on the radicals, is it subtraction(addition)!?
Hope I made sense...!!
