Question

Aratati ca (2+1/3-1/5)15*16 +3√(-8)= 0

Answer 1

Explicație pas cu pas:

$(2 + \frac{1}{3} - \frac{1}{5} ) \times 15 \div 16 + \sqrt[3]{ - 8} = \\ ( \frac{2 \times 15}{15} + \frac{1 \times 5}{15} - \frac{1 \times 3}{15}) \times 15 \div 16 + ( - 2) = \\ \frac{30 + 5 - 3}{15} \times 15 \div 16 - 2 = \\ \frac{32}{15} \times \frac{15}{1} \div \frac{16}{1} - 2 = \\ \frac{32 \times 15}{15 \times 1} \times \frac{1}{16} - 2 = \\ \frac{32}{1} \times \frac{1}{16} - 2 = \\ \frac{32}{16} - 2 = \\ 2 - 2 = 0$
