How do you evaluate (\frac { - 7} { 5} x ^ { 2} y ) \times ( \frac { 3} { 2} x y ^ { 2} ) \times ( \frac { - 6} { 5} x ^ { 3} y ^ { 3} )(75x2y)×(32xy2)×(65x3y3)?

color(blue)(63/25*x^6*y^6)6325x6y6

Explanation:

We have

color(red)((-7/5*x^2*y)*(3/2*x*y^2)*(-6/5*x^3*y^3))(75x2y)(32xy2)(65x3y3)

The problem has just one term with three factors.

We will now group the like terms to simplify.

We are going to group the numeric values first, followed by the x.termsx.terms, followed by y.termsy.terms.

rArr color(red)((-7/5*3/2*-6/5) (x^2*x^1*x^3)(y^1*y^2*y^3))(753265)(x2x1x3)(y1y2y3)

We will be using the following formula

color(green)(a^m*a^n = a^ (m+n))aman=am+n

rArr color(red)(126/50* (x^6)(y^6))12650(x6)(y6)

rArr color(blue)(63/25* (x^6)(y^6))6325(x6)(y6) our final answer
