Answer 1

${40}^{2} + {2 }^{2} = 1600 + 4 = 1604$

${20}^{2} + 23 times 100 = 400 + 2300 = 2700$

$(50 + 846) div {4}^{2} = 896 div 16 = 56$

$( {2}^{2} + 1000) times 10 = 4000 times 10 = 40000$

${20}^{2} times 3 + 200 = 400 times 3 + 200 = 1200 + 200 = 1400$

${90}^{2} div 9 + 546 = 8100 div 9 + 546 = 900 + 546 = 1446$

${70}^{2} div 10 + 545 = 4900 div 10 + 545 = 490 + 545 = 1035$

${80}^{2} div 200 + 251 = 6400 div 200 + 251 = 32 + 251 = 283$
