Hi There!
Exponents are used in math so its easier to multiply. For example if you have to do 8 * 8 * 8 * 8 * 8 * 8 * 8 * 8, then to make it easier to multiply you could change into the exponent form

that is what exponents are used for in math
Hope This Helps :)
Answer: -200
<u>Step-by-step explanation:</u>
P(t) = 800t - t²
P(600) = 800(600) - (600)²
= 480,000 - 360,000
= 120,000
P(400) = 800(400) - (400)²
= 320,000 - 160,000
= 160,000
