The standard form of a complex number is a+bi. So the standard form of the negative square root of 5i is 0-√(5i).
math and algebra
1/(2 + 5i) (multiply both the numerator and the denominator by 2 - 5i)= 1(2 - 5i)/(2 + 5i)(2 - 5i)= (2 - 5i)/(4 - 25i2) (substitute -1 for i2)= (2 - 5i)/(4 + 25)= (2 - 5i)/29= 2/29 - (5/29)i
1/(3+5i)=(3-5i)/((3+5i)(3-5i))=(3-5i)/(9+25)=(3-5i)/34

Welcome to the world of imaginary and complex numbers. i is defined to be a number such that i2 = -1. i is imaginary ( that is not real) 5i is i+i+i+i+i . There is no simpler form than 5i . Please see the attached link for more about imaginary numbers.
0 + 5i Its complex conjugate is 0 - 5i
