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

answer: x= -2y

step-by-step explanation:
