Rewrite in a simplest exponential form. show work.

(-4n^(2))*  (5n^(7)):-20n to the power of 9

(2x)^(3)*(5x^(4 ))^(2): 200x to the power of 11

the mean and mad

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
