Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
1 is 12/12 __ 12/12 + 5/12 is 17/12
3 is 12/4 __ 12/4 + 1/4 is 13/4 __ to get a common denominator, multiply the top and bottom by 3 __ 13/4 is 39/12
17/12 - 39/12 is -22/12 which reduces to -11/6 or -1 5/6 as a mixed number
-5squared is negative __ -25
__ an exponent is associated with the quantity it is written next to
__ without parentheses, the negative sign is not included
__ (-5)squared would be positive 25
ABsquared is A times B times B; NOT AB times AB
