Re: math

Are those signs supposed to be square root signs?

Re: math

15√50 + 8√210
=  15√25 √2 + 8√210   broke down √50, but 210 does not break into two factors where one is a perfect square
=  15(5)√2 + 8√210   evaluated √25 to be 5
=  75√2 + 8√210   multiplied 15 by 5

That's as far as it simplifies without going to decimals.
