Best ResponseYou've already chosen the best response.0a negative exponential means it is actually 1/ the exponential \[7*\frac{ 1 }{ x ^{8} } * 6 * x ^{3} = 42 * \frac{ x^{3} }{ x^{8} }\]

Best ResponseYou've already chosen the best response.0\[(2x^8) \times 3y^9 \times 2x^4 = 4 x^{12} \times 3 y^9=12 x^{12}y^9\] yes, d) for second one
