1. Evaluate the following exponentials with explanations. You may need to use a calculator with a Y x key.
EXAMPLE: X $- 1 / 4$ . If X = 4, this gives _0.7071. Compute to two decimal places or more.
a. X $- 1 / 5$ , When X = 2, this gives .
b. X 1 , When X = 4, this gives .
c. X $1 / 2$ , When X = 64, this gives .
d. X $3 / 4$ , When X = 2, this gives __.
My last question was rejected with the explanation that their is no formulas that go with a-d. This is the exact question the instructor asked us to work on.
