1. Write the C expression to calculate the value of e raised to the 3.5 power.
2. Write the C expression to calculate the absolute value of a^2 - b^2.
3. Write the C expression to calculate the square root of x * y + 2.
4. (Question in image down below). The OPTIONS from the list for all expressions are: -3, 5, 12, -2, 20, 9, 0, 2, 7, -12, -9, -7, -1, -4, -6, 4, 24, 1, 3, 11. Select one option for each expression below.
Evaluate each expression, assuming w=1, x=3, y=4, and z=-2 then select the correct answer from the list. Assume that each expression is evaluated independently (i.e. if a variable is modified in one expression, it does not affect another expression).
