I am slightly confused. What exactly is the question?
The top part equals 1 because anything to the power of zero equals one. then for the second one bring every variable with a negative exponent to the top and leave the 2 at the bottom
Answer:
5
Step-by-step explanation:
If their average is 6 and there are three numbers in total, the total sum of the three numbers would be:
6×3 = 18
You know that two of them is 6 and 7, so you can find the last number easily.
18-6-7 = 5
The answer would be 16
11 + (8-3)^2 - 20 = 16
