a)5 × { 7 + 3 × [ 46 + 6 × ( 27 - 32 : 4 )]}
5 × { 7 + 3 × [ 46 + 6 × ( 27 - 8 )]}
5 × { 7 + 3 × [ 46 + 6 × 19 ]}
5 × { 7 + 3 × [ 46 + 114 ]
5 × { 7 + 3 × 160 }
5 × { 7 + 480 }
5 × 487 = 2435 ;
b) ( 2⁸ )² : 2¹⁶ × ( 3² - 1 ) - 3⁰ × 2²
2¹⁶ : 2¹⁶ × ( 9 - 1 ) - 1 × 4
1 × 8 - 4
8 - 4 = 4 ;
c) ( 3¹⁹ × 25⁹ )² : 15³⁶
( 3¹⁹ × 25⁹ )² / 15³⁶
( 3¹⁰ × 3⁹ × 25⁹ )² / 15³⁶
( 3¹⁰ × [ 3 × 25 ]⁹ )² / 15³⁶
( 3¹⁰ × 75⁹ )² / 15³⁶
3²⁰ × 75¹⁸ / 5³⁶ × 3³⁶
15¹⁸ × 5¹⁸ / 5³⁶ × 3¹⁶
15¹⁸ / 5¹⁸ × 3¹⁶
3¹⁸ × 5¹⁸ / 5¹⁸ × 3¹⁶
3¹⁸ / 3¹⁶ = 3² = 9
sper că te-am ajutat :)
