575.00= 100% 575 divided by 100= 5.75 times 25= 143.75 So then 575.00 - 143.75 = 431.25 (the discount was 143.75, and her new total would be 431.25)
So first you would evaluate the power making the 4^3=64 then keep the rest of the problem the same.... then add the numbers 64+8 since their the whole numbers and that would equal 72 so now the problem should be 72-9/y. After that you write all the numerators above the common denominator making the final answer to be 72y-9/y
Degree of ploynominal is the largest exponent you find, which is here the 4x to the 6th. there are only two terms here.
