Question

pls answer if you can ok ​

Answer 1

Step-by-step explanation:

$\frac{ (0.02) ^ { 2 } -(0.001) ^ { 2 } }{ 0.02-0.001 }$

$\frac{0.0004-0.001^{2}}{0.02-0.001}$

$\frac{0.0004-0.000001}{0.02-0.001}$

$\frac{0.000399}{0.02-0.001}$

$\frac{0.000399}{0.019}$

$\frac{399}{19000}$

$\frac{21}{1000}$

Right answer-

$\frac{3 \cdot 7}{2 ^ {3} \cdot 5 ^ {3}} = 0.021$
