question

why are the following expressions not monomials?

1) 3cd^x

a. the variable is in the denominato

2) x+2w

c. the expression is not a product.

3) 3/h

a. the variable is in the denominator

4) ab^-1

c. the expression is not a product.

hope this !

step-by-step explanation:

assume that y=mx+n

you may see as , where

in we change places of numerator and denominator, then we insert an opposite sign

and substitute m=-1/3 in the equation y=mx+n

point (4,2), so we substitute x=4, y=2 to the equation and calculate

the answer is
