0,01÷10⁻³+(2-√7)²-0,12÷3\10³

Answer 1

0,01÷10⁻³+(2-√7)²-0,12÷3\10³

[tex]0,01:10^{-3}+(2- \sqrt{7})^{2}-0,12: \frac{3}{10^{3} }= [/tex]

[tex]= \frac{1}{100}:( \frac{1}{10})^{3}+4-4 \sqrt{7}+7- \frac{12}{100}* \frac{1000}{3}= [/tex]

$= \frac{1}{100}*1000+11-4 \sqrt{7}- \frac{4}{1}* \frac{10}{1}=$

[tex]=1*10+11-4 \sqrt{7}-40= [/tex]

$=-21-4 \sqrt{7}$
