Answer 1

$\huge{\tt{\underline{\blue{answer}}}}$

1. 325
2. 2520

Answer 2

> First:

$\sf{5{\times}{\{}13+[(2-1+90){\times}7]{\}}÷10}$

= $\sf{5{\times}{\{}13+[(2+89){\times}7]{\}}÷10}$

= $\sf{5{\times}{\{}13+[(91){\times}7]{\}}÷10}$

= $\sf{5{\times}{\{}13+(637){\}}÷10}$

= $\sf{5{\times}(650)÷10}$

= $\sf{(3250)÷10}$

$\Rightarrow$$\Large{\underline{\red{325}}}$

> Second:

$\sf{{\{}2+[{(6-1)}^{3} {\times} 2]{\}} {\times} 10}$

= $\sf{{\{}2+[{(5)}^{3} {\times} 2]{\}} {\times} 10}$

= $\sf{{\{}2+[125 {\times} 2]{\}} {\times} 10}$

= $\sf{{\{}2+[250]{\}} {\times} 10}$

= $\sf{252{\times} 10}$

$\Rightarrow$$\Large{\underline{\red{2520}}}$

‎

> Third:

$\sf {34 ÷ [{(4-3+2)}^{2} {\times} 4]}$

= $\sf {34 ÷ [{(4-5)}^{2} {\times} 4]}$

= $\sf {34 ÷ [{(-1)}^{2} {\times} 4]}$

= $\sf {34 ÷ [1 {\times} 4]}$

= $\sf {34 ÷ 4}$

$\Rightarrow$$\Large{\underline{\red{8.5}}}$
