Question

30 – (2 + 1)²+ 2³ = *

q) [ 4² + ( 5 – 3)³] / ( 9 – 7)³ = *
​

Answer 1

Resposta:

$30 - (2 + 1) {}^{2} + {2}^{3} \\ 30 - {3}^{2} + 8 \\ 30 - 9 + 8 \\ 29$

$\frac{ {4}^{2} + (5 - 3) {}^{3} }{(9 - 7) {}^{3} } \\ \frac{ {2}^{4} + {2}^{3} } { {2}^{3} } \\ \frac{16 + 8}{8} \\ \frac{24}{8} \\ 3$
