Perform the indicated operations and write the result in standard form:





√-36 + √-81





(a) -15


(b) 54i


(c) -15i


(d) 15i

Perform the indicated operations and write the result in standard form:?
it would be d. the i is the symbol for an imaginary number, since both are square roots of negative numbers, you do the actual square root of the positive number, then put that number times i. square root of 36 is 6, so sq root of -36 is 6i. square root of -81 would be 9i. 6i + 9i is 15i.
