The term "sqrt" refers to the square root function, which calculates the value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because (3 \times 3 = 9). The square root is typically denoted as ( \sqrt{x} ), where ( x ) is a non-negative number. If ( x ) is negative, the square root is not defined in the realm of real numbers, but it can be represented in terms of imaginary numbers.

What is the absolute value of 7 5i?
The absolute value of 7± 5i = sqrt(72 + 52) = sqrt(49 + 25) = sqrt(74) = 8.602, approx.
What is the absolute value of 2 4i?
The absolute value of a complex number ( a + bi ) is given by the formula ( \sqrt{a^2 + b^2} ). For the complex number ( 2 + 4i ), the absolute value is calculated as follows: ( |2 + 4i| = \sqrt{2^2 + 4^2} = \sqrt{4 + 16} = \sqrt{20} = 2\sqrt{5} ). Thus, the absolute value of ( 2 + 4i ) is ( 2\sqrt{5} ).
