Final answer:
The given expression (-3) (-3) (-3) (-3) multiplied by 7.7.7.7.7.7 can be expressed using exponents as ((-3)^4) (7^6), representing four occurrences of -3 and six occurrences of 7.
Step-by-step explanation:
The expression (-3) (-3) (-3) (-3) multiplied by 7.7.7.7.7.7 using exponents can be written as ((-3)^4) (7^6). Here we have four occurrences of -3 and six occurrences of 7. When we use exponents, we express repeated multiplication of the same number as a base raised to the power of how many times it is multiplied by itself. Therefore, -3 multiplied by itself four times is written as (-3)^4, and 7 multiplied by itself six times is written as 7^6.
