When dividing two terms with the same base, subtract the exponent in the denominator from the exponent in the numerator: Power of a Power: To raise a power to a power, multiply theexponents. 

Answer 2

$\bf (2x^2y^3)^2(3y)\implies (2x^2y^3)^2(3y^1)\implies (2x^{2\cdot 2}y^{3\cdot 2})(3y^1) \\\\\\ 2x^4y^63y^1\implies 2\cdot 3x^4y^{6+1}\implies 6x^4y^7$
