j = i in the expressions. Please show the work. Thank you!

I need help with the following questions. j = i in the expressions. The expressions are attached as images below. Please show the work. Thank you!

1) Rewrite each complex number in the expression using Euler's Formula and then perform the indicated operations. Write the final answer using both Euler's Formula and in standard form. Round the solution to three decimal places if needed.(Expression starting with (2+j)^2)

2) Perform the indicated operation and show the result using Phasor Notation.(Expression starting with 3e.)

3) Perform the indicated operation and show the result using both Euler's Formula and Phasor Notation.(Expression starting with z = 1.)

4) Find all of the exact solutions to the equation. Show the answers using both Euler's Formula and Phasor Notation.(Expression starting with 2x^4.)

5) Find all of the seventh roots of -1. Show the exact answers in Trigonometric Form.
