Answer 1

$1)2a^{-2} *3a^{4}=\frac{2}{a^{2}}*3a^{4}=\frac{2*3a^{4}}{a^{2}} =6a^{4-2}=6a^{2}\\\\2)24a^{5}:(6a^{-3})=24a^{5}:\frac{6}{a^{3}}=\frac{24a^{5}*a^{3}}{6}=4a^{5+3} =4a^{8}$

$3)(2c^{-3})^{2}=4c^{-6}=\frac{4}{c^{6}}\\\\4)2(3^{-3}b^{3})^{2}3b^{-4} =2*3^{-6}b^{6}*3b^{-4}=\frac{2*3*b^{2}}{3^{6} }=\frac{2b^{2}}{3^{5} }=\frac{2b^{2}}{243}$
