Question

how do I solve a pythagorean theorem problem when one of the sides is the square root of 15?

Answer 1

The same way you'd solve it if one of the sides was 4. Just treat the \(\sqrt{15}\) like any other number. (Cause it is)

Answer 2

Won't be a problem once u have squared it...

Answer 3

once i square it I get 15

Answer 4

There u go then...

Answer 5

ok, thanks! i was making it harder than it is

Answer 6

what if the number is 3 square root of 2?

Answer 7

\[(3\sqrt{2})^2 = (3\cdot \sqrt{2})^2 = 3^2 \cdot \sqrt{2}^2 = 9 \cdot 2 = 18\]

Answer 8

great

Answer 9

when you have 3x squared times y, do you square the x, then multiply by 3, then multiply by y? Or multiply 3 by x then square?
