Answer: (66/11)^3-6*8 = 168
10/7+28-51/2 = 23.93
Explanation:
First set:
(66/11)^3-6*8
(66/11)=6
(6)3-6*8
6^3=216
216-6*8
6*8=48
216-48= 168
Second Set:
10/7+28-51/2
= 206/7-5.5
= 23.928571
we would want to round that answer to 23.93
optional answers:
24
23.9
23.929
etc.
There's your answer
correct me if I'm wrong, or if this wasn't what you were looking for
Good Luck!
Edit:
the exponent is the number 3 also for the 1 question and for the 2 question the 10 and the 7 the a fraction and the 1 and two is a fraction
