Answer 2

Explicație pas cu pas:

$\bf 10^{2} - \big(7^{3} \cdot7^{3} \big)^{3}:49^{8} =$

$\bf 10^{2} - \big(7^{3 + 3} \big)^{3}:\big(7^{2} \big)^{8} =$

$\bf 10^{2} - \big(7^{6} \big)^{3}:7^{2 \cdot8} =$

$\bf 10^{2} -7^{6 \cdot3}:7^{16} =$

$\bf 100 -7^{18}:7^{16} =$

$\bf 100 -7^{18 - 16} = 100 -7^{2} =$

$\bf 100 -49 = \red{ \underline{ \: 51 \: }}$
