The answers for question 4 on the unit 2 test are presented as such:

2^16

Is this 2 to the 16th power?

Is this 2 times 16?

I’m trying to understand. Thanks!

a^n is “a” raised to the nth power. To show multiplication, you would typically write a\*n.

For test security, you may want to change the values in your original question.
