## Why is the square root of I?

Square roots Because the real and imaginary parts are always separate, we regroup the terms: x2 − y2 + 2i x y = 0 + i. and by equating coefficients, real part and real coefficient of imaginary part separately, we get a system of two equations: … Thus, the square roots of i are the numbers 1/√2 + i/√2 and −1/√2 − i/√2 .

## Is 39 a rational number?

For 39 to be a rational number, the quotient of two integers must equal 39. … The number 39 can be expressed as 39/1 where 39 is the numerator and 1 is the denominator. Thus, the answer to the question “Is 39 a rational number?” is YES.

## Why is 38 not a prime number?

For 38 to be a prime number, it would have been required that 38 has only two divisors, i.e., itself and 1. However, 38 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 38 = 2 x 19, where 2 and 19 are both prime numbers.

## Is 40 a square number?
