For example, b = 5 is a square root of 25. A complex number is defined as a number in the form of a + bi where a and b are both defined as real numbers. 1) i + 6i 7i 2) 3 + 4 + 6i 7 + 6i 3) 3i + i 4i 4) −8i − 7i −15 i 5) −1 − 8i − 4 − i −5 − 9i 6) 7 + i + 4 + 4 15 + i 7) −3 + 6i − (−5 − 3i) − 8i 2 + i 8) 3 + 3i + 8 − 2i − 7 4 + i 9) 4i(−2 − 8i) 32 − 8i 10) 5i ⋅ −i 5 11) 5i ⋅ i ⋅ −2i 10 i Activity: Square Roots and Complex Numbers De nition of a Square Root: If a is a real number, then b is said to be a square root of a if b2 = a. Addition / Subtraction - Combine like terms (i.e. (R 3 and R 4 are in series with each other but in parallel with R 2, so do 1 + 1 , get an answer and then add the two resistors that are in series.) MEI Online Resources provide this hexagonal jigsaw activity on Complex Numbers. 6. Just in case you forgot how to determine the conjugate of a given complex number, see the table below: Conjugate of a Complex Number. Imaginary numbers arise frequently in mathematics, but in order to do much with them we need to know more about the complex plane and the rectangular form of complex numbers. Complex Numbers are useful in representing a phenomenon that has two parts varying at the same time, for example an alternating current. Students will evaluate the numerator and the denominator and type them in separately. Complex numbers - Spot the errors Find … form).
