You need to change the variable `y^2` from numerator in `x^2 ` because it is of no use to write the numerator in the given form if the bases y would be alike.

You need to isolate the constant terms, the terms containing powers of x and the terms containing powers of y such that:

`(-18/6) = -3` constant terms

`(x^2)/(x^7)` terms containing variable x

`(y^4)/(y^2) ` terms containing variable y

You need to use the property of division of powers that have like bases such that:

`(x^2)/(x^7) = x^(2-7) = x^(-5)`

Using the negative power property yields:

`x^(-5) = 1/(x^5)`

`(y^4)/(y^2) = y^(4-2) = y^2`

Multiplying the results of the three groups yields:

`(-18x^2y^4)/(6x^7y^2) = -3(y^2)/(x^5)`

**Hence, simplifying the fraction to its lowest terms yields:**

**`(-18x^2y^4)/(6x^7y^2) =-3*y^2*x^(-5)` **

The expression `(-18x^2y^4)/(6x^7y^2)` has to be simplified.

`(-18x^2y^4)/(6x^7y^2)`

=> `-3*x^-5*y^2`

=> `(-3*y^2)/x^5`

**The expression `(-18x^2y^4)/(6x^7y^2) = (-3*y^2)/x^5` **

thank you for your help :)
