Answer 1

$x^ alpha cdot x^ beta =x^{ alpha + beta } \ frac{x^ alpha }{x^ beta } =x^{ alpha - beta } \ (x^ alpha )^ beta =x^{ alpha beta }$

$a^{0.6}cdota^{3.4}=a^{0.6+3.4}=a^4 \ a^{- frac{3}{7} }a^{ frac{5}{14} }=a^{- frac{3}{7}+frac{5}{14} }=a^{- frac{6}{14}+frac{5}{14} }=a^{- frac{1}{14}} \ (a^ frac{5}{17} )^{ frac{3}{5} }=a^ {frac{5}{17}cdot frac{3}{5} }=a^frac{3}{17}$

$a^{ frac{7}{15} }:a^frac{1}{6} =a^{ frac{7}{15}-frac{1}{6}}=a^{ frac{14}{30}-frac{5}{30}}=a^ frac{9}{30} =a^ frac{3}{10}= a^{0.3} \ (a^{-0.8})^4cdot(a^{-1.4})^{-2}:(a^{0.4})^{-6}= a^{-0.8cdot4}cdot a^{-1.4cdot(-2)}:a^{0.4cdot (-6)}= \ =a^{-3.2}cdot a^{2.8}:a^{-2.4}=a^{-3.2+2.8-(-2.4)}=a^2 \ (a^frac{5}{18}a^ frac{10}{27})^ frac{9}{5}=a^{(frac{5}{18}+frac{10}{27})cdotfrac{9}{5} } = a^{(frac{15}{54}+frac{20}{54})cdotfrac{9}{5}}=a^{frac{35}{54}cdotfrac{9}{5}}= a^{frac{7}{6}$
