Question

simplify :- (0.22)*4 (0.222)*3/(0.2)*5 (0.2222)*2​

Answer 1

Correct answer is $1.622$

Explanation:

$(\frac{22}{100})^{4} \times (\frac{222}{1000})^{3}\times (\frac{10}{2})^{5}\times (\frac{10000}{2222})^{2}$

$= (\frac{22^{4}}{10^{8}}) \times (\frac{222^{3}}{10^{9}}) \times (\frac{10}{2})^{5}\times (\frac{10^{8}}{2222^{4}})$

$= (\frac{22^{4}\times 222^{3}}{2^{5} \times 2222^{4}})\times 10^{-4}$

$= 16222.26 \times 10^{-4}$

Correct answer is $1.622$
