Question

When 27 times x squared times z all over negative 3 times x squared times z to the sixth power is completely simplified, the exponent on the variable z is _____.

Answer 1

5

Explanation:

Did the worksheet and got it correct. If you look at the other answers for this question, many of them say -5 but they are not right, because an equation is not considered simplified if it has negative exponents. Therefore, simplify the answer of -5 further to get 5.

`27x^z z^1/-3x^(2) z^6\\27z/-3z^6\\-9z/z^6\\-9/z^5\\9z^5`

Answer 2

7

When you do 27 times x squared times z all over -3, then times that by x squared times z to the sixth power, you get -9x^4z^7
