a We want to simplify the given numeric expression using the imaginary number i. To do so, we will first recall that the imaginary unit i is the complex number whose square is - 1.
i^2=- 1
We can simplify the given expression by using the above definition and combining like terms.
b Like in Part A, we want to simplify the given numeric expression using the imaginary number i. To do so, we will first recall that the imaginary unit i is the complex number whose square is - 1.
i^2=- 1
We can simplify the given expression by using the above definition and combining like terms.
c Like in Parts A and B, we want to simplify the given numeric expression using the imaginary number i. To do so, we will first recall that the imaginary unit i is the complex number whose square is - 1.
i^2=- 1
We can simplify the given expression by using the above definition and combining like terms.
d Like in previous parts, we want to simplify the given numeric expression using the imaginary number i. To do so, we will first recall that the imaginary unit i is the complex number whose square is - 1.
i^2=- 1
We can simplify the given expression by using the above definition and combining like terms.
