Question

. Simplify the following.
​

Answer 1

${\underline{\sf{Solution\:of\:a:}}$

${\rightarrow{\sf{Solution\:Steps:}$

${\boxed{\bullet{\sf{\:\:\frac{3^6xa^8b^5}{3^5xa^4b^4}}}}$

${\boxed{\bullet{\sf{\:\:\frac{3^6a^8b^5}{3^5a^4b^4}}}}$

${\boxed{\bullet{\sf{\:\:\:3^{6-5}a^{8-4}b^{5-4}}}}$

${\boxed{\bullet{\sf{\:\:\:3^{1}a^{8-4}b^{5-4}}}}$

${\boxed{\bullet{\sf{\:\:\:3^{1}a^{4}b^{5-4}}}}$

${\boxed{\bullet{\sf{\:\:\:3^{1}a^{4}b^{1}}}}$

${\boxed{\bullet\:\:{\Rightarrow{\sf{\:\:\:3a^4b}}}}}$

${\underline{\sf{Solution\:of\:b:}}$

${\rightarrow{\sf{Solution\:Steps:}$

${\boxed{\bullet{\sf{\:\:\{(3)^{-3}x5^3\}\div6^0}}}}$

${\boxed{\bullet{\sf{\:\:\frac{\frac{1}{27}\:x\:5^3}{6^0}}}}$

${\boxed{\bullet{\sf{\:\:\frac{\frac{1}{27}\:x\:125}{6^0}}}}$

${\boxed{\bullet{\sf{\:\:\frac{\frac{125}{27}}{6^0}}}}$

${\boxed{\bullet{\sf{\:\:\frac{\frac{125}{27}}{1}}}}$

${\boxed{\bullet{\sf{\:\:\frac{125}{27}}}}$

${\boxed{\bullet\:\:{\Rightarrow{\sf{\:\:\:4.629}}}}}$

${\boxed{\bullet\:\:{\Rightarrow{\sf{\:\:\:\approx4.63}}}}}$
