Question

7 la puterea 65 ori 7 la puterea 62 +(2 la puterea 2)totul la puterea a treia minus 5 la puterea 3 la=​

Answer 1

Răspuns:

${7}^{65} \times 7^{62} + ( {2}^{2} ) {}^{3} - {5}^{3}$

${7}^{65} \times {7}^{62} + (2 {}^{3} {}^{} { \times }^{2} ) - {5}^{3}$

${7}^{65} \times {7}^{62} + {2}^{6} - {5}^{3} =$

${7}^{65 - 62} + {2}^{6} - {5}^{3} =$

${7}^{3} + {2}^{6} - {5}^{3}$

$7 \times 7 \times 7 + 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 + 5 \times 5 \times 5$

$343 + 128 + 125$

$471 + 125 = 596$
