Question

(-2)2-[-23- raiz quadrada 16.(23-10)]:171

Answer 1

$( - 2) \times 2 - \frac{( - 23 - \sqrt{16 } \times (23 - 10)}{171}$
$- 4 - \frac{( - 23 - 4 \times 13)}{171} = - 4 - \frac{75}{171} =$
$\frac{- 4 \times 171 - ( - 75)}{171}$
$\frac{ - 684 + 75}{171}$

$- 609 \div 171 =$
$\frac{-203}{57}$
