What is 8*8*8*8 written using an exponent

8 to the power of 4      

Step-by-step explanation:

An exponent tells us how many times a number is multiplied by itself. Since 8 is multiplied four times by itself, its exponential form will be 8⁴.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
