Question

ME AJUDEM POR FAVOR ​

Answer 1

Resposta:

a)

$\frac{25}{5} + 4 \times 3 - {6}^{2} = - 19$

$5 + 4 \times 3 - {6}^{2} = - 19 \\ 5 \times 12 - {6}^{2} = - 19 \\ 17 - {6 }^{2} = - 19 \\ 17 - 36 = - 19$

b)

$\frac{12}{4} + {9}^{2} \times {2}^{2} = 327 \\ 3 + {9}^{2} \times {2}^{2} = 327 \\ 3 + 81 \times {2}^{2} = 327 \\ 3 + 81 \times 4 = 327 \\ 3 + 324 = 327$

c)

$65536 + 34 - \frac{ \sqrt{576} }{3 } = 65562 \\ 65570 - \frac{ \sqrt{576} }{3} = 65562 \\ 65570 - \frac{24}{3} = 65562 \\ 65570 - 8 = 65562$

d)

$\frac{3 \times 12 + 6 \sqrt{64} }{3} = 28 \\ \frac{36 + 6 \sqrt{64} }{3} = 28 \\ \frac{36 + 6 \times 8}{3} = 28 \\ \frac{36 + 48}{3} = 28 \\ \frac{84}{3} = 28$
