Question

Which of the following statements is not true?

1.) xxxxxx = x^6

2.) AAAAAAABBBBB = A^7B^5

3.) b^6c^6 = (bc)^6

4.) x^5y^5z^5 = xyz^5

Answer 1

not true

answer is
x^5y^5z^5 = xyz^5

should be
(xyz)^5

Answer 2

The answer is number 4.
xyz^5 is saying that only z is raised to the 5th power. There would either need to be parentheses around xyz or leave it with each letter individually raised.
