Hi Carolina,
Actually I don't think that any of the choices is correct. Lets analyze the statement
C is 10 more then the square of the quotient of the sum of x and y , and the
product of x and y.
It says
C is 10 more than something.
This
C = something + 10
Options B., C, and D. are of this form but A. is not. Thus A. is not correct.
Look ath the statement again
C is 10 more then the square of the quotient of the sum of x and y , and the
product of x and y.
I know that the sum of x and y and the
product of x and y both go with the quotient since the quotient takes two parameters. (We know that the quotient of 4 and 3 is ^{4}/_{3} but the quotient of 4 makes no sense.) Thus
the quotient of the sum of x and y , and the
product of x and y
is
^{x + y}/_{xy}
and hence C. is not correct.
The statement now reads
C = the square of ( ^{x + y}/_{xy}) + 10
which is
C = ( ^{x + y}/_{xy})^{2} + 10
Cheers,
