Question 2

Simplify the following term:

Select and check your answer...

A. 1/a
B. a²
C. a
D. 1/a²

Fractions are just basically numbers. Therefore the exponent laws are still applicable.

Let's use the first exponent law to simplify this term.

Now, this term becomes: 

Alright, '+' sign multiply by '-' sign gives a '-' sign.

Hence, we have:

Now, since both of the denominators are the same, we can combine these two fractions into one.

Hence, this term becomes: 

Now, 2 divides by 2 gives 1. Rather than leaving the answer as a¹. It's neater to write a¹ as a. 







Clearly, the answer is C.
