Thanks Reiny

How ado I simplify?
(3i�ã5)^

you forgot the exponent.

it says (3i*ã5)2

(3i√5)^2

= 9i^2(5)
= -45 , remember i^2 = -1

To simplify the expression (3i�ã5)^, we need to clarify what you mean by the exponent "^". Could you please provide the specific value or operation you want to apply to the expression?
