Question

Fraction Form (Rational Expressions)

Multiply and simplify the product

8y^6 / 9r^2 * 81r^6 / 64y

Answer 1

(9y^5r^4)/8

Answer 2

Final answer is 9y^5 * r^4/8

The 8 in the numerator divides into the 64 in the denominator leaving
y^6/9r^2 * 81r^6/8y

The y in the denominator divides into the y^6 in the numerator leaving
y^5/9r^2 * 81r^6/8

The 9 in the denominator divides into the 81 in the numerator leaving
y^5/r^2 * 9r^6/8

The r^2 in the denominator divides into r^6 in the numerator leaving
y^5 * 9r^4/8 or 9y^5 * r^4/8

Much easier to see if the fractions are written vertically rather than horizontally
