5\times \left(3i\right)\sqrt{5}
Factor -45=\left(3i\right)^{2}\times 5. Rewrite the square root of the product \sqrt{\left(3i\right)^{2}\times 5} as the product of square roots \sqrt{\left(3i\right)^{2}}\sqrt{5}. Take the square root of \left(3i\right)^{2}.
15i\sqrt{5}
Multiply 5 and 3i to get 15i.
