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).

9^3 = (3^2)^3 = 3^(2×3) = 3^6 = 729
3^5*4^5 = (3*4)^5 = 12^5
81 to the power of 3/4 = 27
23 + 32 = 8 + 9 = 17
5 to the 3rd power, written as (5^3), is calculated by multiplying 5 by itself three times: (5 \times 5 \times 5). This equals 125. Therefore, (5^3) simplified is 125.
