có thì sao

???

bạn giúp mình đi mk tích cho

bạn hỏi toàn câu hỏi dễ

c,\(\left(-3\right)^2\).(\(\frac{3}{4}\)-0,25)-|\(3\frac{1}{2}\)-\(1\frac{1}{2}\)|

=9.(\(\frac{3}{4}\)-\(\frac{1}{4}\))-|\(\frac{7}{2}\)-\(\frac{3}{2}\)|

=9.\(\frac{2}{4}\)-\(\frac{4}{2}\)

=9.\(\frac{1}{2}\)-2

=\(\frac{9}{2}\)-2

=\(\frac{9}{2}\)-\(\frac{4}{2}\)

=\(\frac{5}{2}\)
