Question

7 la puterea 38÷7la puterea37÷7+3 la puterea45÷3la puterea44×3

Answer 1

$7 {}^{38} \div 7 {}^{37} \div 7 + 3 {}^{45} \div 3 {}^{44} \times 3 =$
$1 + 3 {}^{2} =$
$1 + 9 =$
$10$

Answer 2

7 la putere 38 : 7 la puterea 37 :  7

se copiaza baza 7 si se scad puterile 38-37-1 = 0 => 7 la puterea 0 = 1

3 la putere 45 : 3 la putere 44 x 3

se copiaza baza 3 si puterea devine : 45 -44+1 = 2 => 3 la puterea 2 = 9

1+9=10
