Question

2(5-3i)+i5(3i-2) plsss help me fast​

Answer 1

Given: The correct term must be 2(5-3i)+i^5(3i-2)

To find: The sum of two terms given.

Solution:

• Now we have given the expression as:

                2 ( 5 - 3i ) + i^5 ( 3i - 2 )

• Multiplying the outer terms in brackets, we get:

                10 - 6i + 3i^6 - 2i^5

• Now we know the value of :

               i^6 = i^2 = -1

                i^5 = i

• Now using them, we get:

                10 - 6i + 3(-1) - 2i

                10 - 6i - 3 - 2i

                7 - 8i

Answer:

            So the value of  2(5-3i)+i^5(3i-2)  is 7 - 8i.
