Question

a,( -0,25) .7,9.40 ; b, (3/2)³ . 2³ ; c, ( 1,75 : 7/2 ) .4/5 ; d, 11/2.4 5/3-2 5/3 -11/2 giúp vs ai đug mk tik cho

Answer 1

a, (-0.25) * 7.9 * 40 = [ (-0.25) * 40] * 7.9 = -10 * 7.9 = -79

b, ( 3/2 )^3 * 2^3 = ( 3/2*2) ^3 = 3^3 = 27

c, (1.75 / \(\frac{7}{2}\)) * \(\frac{4}{5}\)= ( 7/4 * 7/2 ) *4/5 = \(\frac{49}{10}\)

d, \(\frac{11}{2}\cdot4\frac{5}{3}-2\frac{5}{3}\cdot\frac{11}{2}\)= \(\frac{11}{2}\cdot\left(\frac{17}{3}-\frac{11}{3}\right)\)= \(\frac{11}{2}\cdot\frac{6}{3}\)= \(\frac{11}{2}\cdot2\)=11
