Is there something like a picture so I can understand better?
B to the second means b * b.
The short hand for b*b is b^2 on this editor or

c to the fourth means c * c * c *c
the short hand for c*c*c*c is c^4 on this editor or

The answer you want is b^2/c^4 in the answer box.
If this is wrong and you have choices, please list them and I will edit or put the answer in a comment.
The product of 26.22 and 3.09 is:
<span>26.22 * 3.09 = 81.0198
The sum of </span><span>3.507, 2.08, 11.5, and 16.712 is:
</span><span>3.507+ 2.08 +11.5+ 16.712 = 33.799
The difference between the product and the sum is:
</span>81.0198 - 33.799 = 47.2208
Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0
