Question

Calcule:

a) 8/3 . 4/3 =

b) (4/3)² =

c) (5/2)² =

d) 4/2 . 6/2 =

Answer 1

$a) \: \frac{8}{3} \times \frac{4}{3} = \frac{8 \times 4}{3 \times 3} = \frac{32}{9} \\ b) \: \frac{4}{3} {}^{2} = \frac{4 \times 4}{3 \times 3} = \frac{16}{9} \\ c) \: \frac{5}{2} {}^{2} = \frac{5 \times 5}{2 \times 2} = \frac{25}{4} \\ d) \: \frac{4}{2} \times \frac{6}{2} = \frac{4 \times 6}{2 \times 2} = \frac{24}{4}$
