Question

\(\sqrt{\dfrac{16}{169}}-\sqrt{13^2-12^2}+\sqrt{\left(-3\right)^2}\)

Answer 1

\(\sqrt{\dfrac{16}{169}}-\sqrt{13^2-12^2}+\sqrt{\left(-3\right)^2}\)

\(=\dfrac{4}{13}-\sqrt{25}+\sqrt{9}\)

\(=\dfrac{4}{13}-5+3\)

\(=\dfrac{4}{13}-\dfrac{65}{13}+\dfrac{39}{13}\)

\(=\dfrac{4-65+39}{13}\)

`=-22/13`

Answer 2

=413−√25+√9=413−25+9

=413−6513+3913=413−6513+3913
