Rewrite 3+4−45−−−−√ as a complex number in the standard form a+bi .(1 point)

We can simplify the expression by first converting the square root of 45 into a complex number.

The square root of 45 is √45 = √(9*5) = √9 * √5 = 3 * √5
So the expression becomes 3 + 4 - 3√5
Now, in the standard form a+bi, we can write it as: 3 + 4 - 3√5 + 0i
