Answer 1

Răspuns

$({2}^{2} \times {3}^{2} - {5}^{2}) \div 11 + {3}^{2} \times {7}^{2} - {4}^{2}$

$((2 \times 3)^{2} - 25) \div 11 + (3 \times 7)^{2} - {4}^{2}$

$({6}^{2} - 25) + 11 + {21}^{2} - {4}^{2}$

$(36 - 25) \div 11 + {21}^{2} - {4}^{2}$

$11 \div 11 + {21}^{2} - {4}^{2}$

$1 + {21}^{2} - {4}^{2}$

$1 + (21 - 4) \times (21 + 4)$

$1 + 17 \times 25$

$1 + 425$

$426$
