52. The absolute value is the nonnegative value of a number. Enclosing vertical bars ( | | ) are the absolute value operator. Using that notation we can state that |a| = a, and |-a| = a. You can also note that |a| (whether a is negative or positive) equals the square root of a squared.
The absolute value of 7± 5i = sqrt(72 + 52) = sqrt(49 + 25) = sqrt(74) = 8.602, approx.
|5 + 12i| = +sqrt(52 + 122) = +sqrt(25 + 144) = +sqrt(169) = 13
