0

Answer 2

Explicație pas cu pas:

$\bf 8389 \cdot16^{2} +8389\cdot30^{2}- 8389\cdot34^{2}=$

$\bf 8389 \cdot \big(16^{2} + 30^{2}-34^{2} \big)=$

$\bf 8389 \cdot \big(256 + 900- 1156 \big)=$

$\bf 8389 \cdot \big(1156- 1156 \big)=$

$\bf 8389 \cdot 0=$

$\red{ \underline{ \: \bf 0 \: }}$

$= = pav38 = =$
