Hello!
the √(-61) is a complex number √61i

But if you wish to find the value of an irrational and imaginary number, I will give you the approximate answer.


√(-61) \to √(-1*61) \to √(-1) * √(61) \to i* √(61) \to i*7,81024...\: \boxed{\approx 7.8i}

well, the square root of a negaitve number will be an imaginary number
that is, i=√-1

so we can write

√(-61)=(√(-1))(√(61))=(i)(√(61))
\sim (i)(7.81) \sim 7.8i
