I WILL GIVE FREE POINTS TO WHOEVER ANSWERS THESE CORRECT Use your exponent rules to express as a single power, 9^4 ÷ 27^2
and
Explain the difference between -2^4 and (-2)^4, and evaluate each power

Step-by-step explanation:

1. 9^4 is 9 x 9 x 9 x 9, so 6561 (big number ik) and 27^ 2 is 27 x 27, so 729. 6561 / 729 is 9

2. When there is (), you include the negative. when you don't, you do the exponents then add the negative the first one would be -16, and the second would be 16 also, but it would be -2 x -2 x -2 x -2 rather than 2 x 2 x 2 x 2

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

noncoplanar points are points that do not lie on the same line.
