Question

\(\frac{1}{2}-\sqrt{\frac{25}{4}}-\left(\frac{1}{3}-2\frac{1}{2}\right)\)

Answer 1

\(\frac{3}{2}\sqrt{\frac{25}{4}}-\left(\frac{1}{3}-\frac{5}{2}\right)\)

=\(\frac{3}{2}.\frac{5}{2}-\left(-\frac{13}{6}\right)\)

=\(\frac{15}{4}+\frac{13}{6}=....\)

Answer 2

1 và 1/ 2 √25/ 4 −(1/ 3 −2 và 1/ 2 )

3/ 2 √25/ 4 −(1/ 3 − 5/ 2 )

=3/ 2 .5/ 2 −(−13/ 6 )

=15/ 4 +13 / 6 =....
