CLEP Pre-Calculus Exam

Question 1

Evaluate (4 - 2i)*(1 - 5i)

-7/15 - 4i/15 -5 + 7i -6 - 22i -4 + 2i

Correct Answer:

-6 - 22i

Question 2

What is the value of the expression (x + yi)(x - yi) if (x + yi) / i = 7 + 9i, where x and y are real numbers?

-130 130 0 26i

Correct Answer:

130

Question 3

Find all complex numbers z that satisfy the equation z + 3z' = 5 - 6i, where z' is the complex conjugate of z.

z = 5/4 - 3i z = 5/4 + 3i z = 5 - 3i z = 5 + 3i

Correct Answer:

z = 5/4 + 3i

Question 4

Define Complex number.

A number with only a real part. A number of the form a + bi, where a and b are real numbers. A number of the form a + i, where a is a real number. A number with only an imaginary part.

Correct Answer:

A number of the form a + bi, where a and b are real numbers.

Question 5

Explain the real and imaginary components of a complex number.

The real part is the constant term, and the imaginary part is the coefficient of i. The real part is the integer part, and the imaginary part is the fractional part. The real part is the coefficient of i, and the imaginary part is the constant term. The real part is the whole number, and the imaginary part is the decimal part.

Correct Answer:

The real part is the constant term, and the imaginary part is the coefficient of i.
