What is an exponent?
I am just confused. I need the definition. Thx

a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).

an exponent is how many times you multiply a number by itself.

Step-by-step explanation:

For example, if there is a 4 with a 3 as an exponent, you would solve 4x4x4, also known as 4 cubed. or if there was a 2 with a 4 as an exponent , you would do 2x2x2x2. Hope this helps :)

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
