Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e. 
is the same
as taking the square root.
- so
is the same as the square root of 
.
For example, taking the square root of 4 will determine:
so the expression becomes
∵ 
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
So, the first 10 suits came with a commission of 5%, so for each suit it was:
250*5%
this is
but this counts for 10 suits, so together his commssion was 10*12.5=125 dollars
and the "extra" 3 suits came with a comittion of 5+3 percent, so 8 percent, which is
for each suit, and 60 in total.
his total comission was 125+60=185 dollars.
Y = 16 because 4x3 = 12 + 4 = 16
This one is A. they are complementary
