Question

8 ³- {9²+[25×(4³÷8-3)]}​

Answer 1

Resposta:

306

$\sf{8 ³- {9²+[25×(4³÷8-3)]}}$

$\sf{512 - ( {9}^{2} + (25( {4}^{3} \div 8 - 3)))}$

$\sf{512 - (81 + (25( {4}^{3} \div 8 - 3))) }$

$\sf{512 - (81 + (25( {2}^{6} \div 8 - 3)))}$

$\sf{512 - (81 + (25( {2}^{6} \div {2}^{3} - 3)))}$

$\sf{512 - (81 + (25( {2}^{3} - 3))) }$

$\sf{512 - (81 + (25(8 - 3)))}$

$\sf{512 - (81 + (25x5))}$

$\sf{512 - (81 + 125)}$

$\sf{512 - 206}$

$\rightarrow \boxed{ \boxed{\sf{306}}} \checkmark$
