# IMSQRT function

The IMSQRT function computes the square root of a complex number.

### Parts of a IMSQRT function

The IMSQRT formula is formatted as =IMSQRT(complex_number).

 Part Description Notes complex_number The complex number to take the square root of.

IMSQRT(2)

IMSQRT("3+2i")

### Notes

• This function is equivalent to using IMPOWER(complex_number, 0.5).
• While it is not possible to use the SQRT function to take the square root of a negative real number, it is possible to use IMSQRT to take the square root of a complex number with a negative real number component.

### Examples

A B
1 Formula Result
2 =IMSQRT(4) 2
3 =IMSQRT("3+4i") 2+i
4 =IMSQRT("3-4j") 2-j
5 =IMSQRT(COMPLEX(3, 4)) 2+i
