Question

Calculați a 1,5•3 b) 12/15:(-5/3) C) (2 1/3) la puterea a doua
Va rog rapidd!!!!!!!

Answer 1

Răspuns:

a)

$1.5 \times 3 = \frac{15}{10} \times 3 = \frac{15 \times 3}{10} = { \frac{45}{10} }^{(5} = \frac{9}{2} = 4.5$

b)

$\frac{12}{15} \div ( - \frac{5}{3} ) = \frac{12}{15} \times ( - \frac{3}{5} ) = - { \frac{36}{75} }^{(3} = - \frac{12}{25} = 0.48$

c)

$2 \frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3} = 2.(3)$

Sper ca te-am ajutat :))))))
