Question

Express as a Monomial in terms of I ??? HOW TO DO PLEASE :O

Answer 1

do you mean i?
i = \[\sqrt{-1}\]

Answer 2

i think so. it's:\[8\sqrt{-36}-4\sqrt{-49}\]

Answer 3

ok, so that's \[8\sqrt{36}\sqrt{-1} - 4\sqrt{49}\sqrt{-1}=(8\times6\times i) - (4\times7\times i)=48i -35i=13i\]

Answer 4

oops should be 48i - 28i = 20i
