Question

qual é o valor da expressão: 4/7x✓49/64 +( 1 - 3/5):3/5 + (1+1/3)

Answer 1

Vou tentar fazer como eu entendi:

4/7x✓49/64 +( 1 - 3/5):3/5 + (1+1/3)

4/7 × 7/8 + 2/5 : 3/5 + 4/3

4/8 + 2/5×5/2 + 4/3

4/8 + 10/10+ 4/3

4/8 + 1 + 4/3

12/8 + 4/3

68/24. simplificando por 2

34/12. por 2

Answer 2

vamos lá...

$\frac{4}{7} \times \sqrt{ \frac{49}{64} }+(1- \frac{3}{5} )\div \frac{3}{5} +(1+ \frac{1}{3} )= \\ \\ \\ \frac{\not4}{\not7} \times \frac{\not7}{\not8_2} +( \frac{5-3}{5} )\div \frac{3}{5} +( \frac{3+1}{3} )= \\ \\ \frac{1}{2} +( \frac{2}{\not5})\times \frac{\not 5}{3} + \frac{4}{3} = \\ \\ \frac{1}{2} + \frac{2}{3} + \frac{4}{3} = \\ \\ \frac{3+4+8}{6} = \frac{15}{6} = \frac{5}{2}$
