{(0.013)^{3}+0.000000343}/{(0.013)^{2}-0.000091+0.000049}

is

Solution:

(2)

{(0.013)^{3}+0.000000343}/{(0.013)^{2}-0.000091+0.000049}

= {(0.013)^{3}+(0.007)^{3}}/{(0.013)^{2}-(0.013 × 0.007)+(0.007)^{2}}

= {(0.013+0.007) ((0.013)^{2}-(0.013 × 0.007)+(0.007)^{2} )}/{(0.013)^{2}-(0.013 × 0.007)+(0.007)^{2}}

=0.013+0.007=0.02
