Question

Plz answer the 4th one

Answer 1

Answer:

$3^{4} / 3^{8} * 3^{-5}$

$3^{4-8} * 3^{-5}$   $(x^{n} / x^{m} ) = x^{n-m}$

$3^{-4+(-5)}$      $x^{m} * x^{n}= x^{m+n}$

$3^{-4-5}$

$3^{-9}$

$\frac{1}{3^{9} }$

Answer 2

Question :-

Simplify :

${3}^{4} \div {3}^{8} \times {3}^{5}$

Solution :

${3}^{4} \div {3}^{8} \times {3}^{5} \\ \\ \rightarrow \: {3}^{4 - 8 } \times {3}^{5} \\ \\ \rightarrow \: {3}^{ - 4} \times {3}^{5} \\ \\ \rightarrow \: {3}^{ - 4 + 5} = {3}^{1} \\ \\ \rightarrow \: 3$

Answer :-

$\rightarrow \: 3$
