Answer:
Divide 108 by 12 since there are 12 inches in a foot.
108 ÷ 12 = 9
20 and -3 equals 17 and 20 times -3 equals -60
1. 5x-y=4
2. -4/3+1/3y-2/3z
3. x=5+1/2y -3/2z
And/or the answer to the whole thing could be that the statement is incorrect.
All you have to do is write a positive number. let's say 4, then write a positive exponent (that's the tiny number in the right corner of the regular number) and then just write a positive exponent less than 4.
So 4 squared
