Simplify 425xy⁴/25xy²
beks73 [17]

We have the expression

\frac{425xy^4}{25xy^2}

We can already simplify x because it's both on the numerator and denominator

\frac{425y^4}{25y^2}

Now we can simplify 425/25 = 17

\frac{17y^4}{y^2}

Remember that

\frac{a^n}{a^m}=a^{n-m}

Then

17y^{4-2}=17y^2

The final result is

17y^2

Multiplying this $75 by 0.90 results in $67.50.  This price reflects both the initial 25% discount and the additional 10% discount.
