Describe how you would use the rules of exponents to simplify (7x?yz) 3. You may indicate an exponent in your answer with ^. For

example, 3x2 y?as 3x^2y^2

343x^6y^3z^3

Step-by-step explanation:

One of the rules of exponents demands:

where a, b, c and m are coefficients.

Furthermore, you use the following rule for exponents of variables that already have an exponent:

Thus, you can apply this rules in the following way:

hence, the answer is 343x^6y^3z^3

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
