Tania Sweeney · Answer 1

(9x²y³) (7xy²)

9 * 7 = 63

x² * x = x^2+1 = x³

y³ * y² = y^3+2 = y^5

(9x²y³) (7xy²) = 63x ³y^5

Sawyer Barton · Answer 2

Remember

(ab) (cd) = (a) (b) (c) (d) = (ac) (bd),

and

(x^m) (x^n) = x^ (m+n)

(9x^2y^3) (7xy^2) =

(9) (x^2) (y^3) (7) (x) (y^2) =

(9) (7) (x^2) (x) (y^3) (y^2) =

(63) (x^3) (y^5) =

63x^3y^5
