Question

simplify.-7XY^2/28X^5_Y

Answer 1

can some help me with this

Answer 2

-7xy^2/28x^5y

When you divide variables, the exponents subtract.
Thus,
for the x exponent
1-5=-4
for the y exponent
2-1=1

for the coefficients
-7/28=-1/4

-1/4(x^-4)y

Following this form:
a^(-b)= 1/(a^b)
So (-1/4)y/x^4
