Question

3. Verifică egalitatea: [100x (123:3-64:2) + (89x4-98 x 3)]: 2=4×100+ 9×9.​

Answer 1

$[100 \times (123:3-64:2)+(89\times4-98\times3)]:2=4\times100+9\times 9$

$[100 \times(41-32)+(356-294)]:2=400+81\\\\(100\times 9+62):2=481\\\\ (900+62):2=481\\\\ 962:2=481\\\\ 481=481\Rightarrow Egalitatea~este~adevarata.$
