Question

can u give this answer briefly​

Answer 1

=39/4+[13/6+{13/3-(3/2+7/4)}]

=39/4+[13/6+{13/3-(6+7/4)}]

=39/4+[13/6+{13/3-(13/4)}]

=39/4+[13/6+{13/3-13/4}]

=39/4+[13/6+{52-39/12}]

=39/4+[13/6+{13/12}]

=39/4+[13/6+13/12]

=39/4+[26+13/12]

=39/4+[39/12]

=39/4+39/12

=117+39/12

=156/12

=13.
