1 and 3/4To add two fractions, combine the numerators when there is a common demominator (then you can also simplify).In the question 7/8 + 7/8 ... there is a common denominator.So you get 14/8This can be simplified to 7/4This can be simplified to 1 and 3/41 and 3/4 is your answer (which is 1.75 in decimal form).

81 to the power of 3/4 = 27
23 + 32 = 8 + 9 = 17
3/4 cannot be simplified further.3/4 cannot be simplified further.3/4 cannot be simplified further.3/4 cannot be simplified further.
(4x4 + y7)/(8x5 + y3) cannot be simplified.
that is simplified
