Answer:
a)1/2^4
Step-by-step explanation:
First solve 2^-4.
Use negative power rule: x^-a = 1/xa
⇒ 1/2^4
Simplify 2^4 to 16
⇒ 1/16
Just evaluate the other options.
The first one is correct.
Here's why:
⇒ Simplify 2^4 to 16.
⇒ 1/16
They have the same steps, therefore making Option A correct.
Note: This is the longer way, there is a easier way of dealing with these types of problems. Example: Without using a calculator problem.
