Răspuns:
Explicație pas cu pas:
a )
( 2⁸ )² : 2² la puterea a 4 a × ( 3² - 1 ) - 3⁰ × 2² = 4
2¹⁶ : 2¹⁶ × ( 9 - 1 ) - 1 × 4 = 4
1 × 8 - 1 × 4 = 4
8 - 4 = 4
b )
( 3¹⁹ × 25⁹ )² : 15³⁶ = 9
( 3¹⁰ × 3⁹ × 25⁹ )² : 15³⁶ = 9
( 3¹⁰ × 75⁹ )² : 15³⁶ = 9
( 3¹⁰ × 75⁹ )² : 5³⁶ × 3³⁶ = 9
( 3²⁰ × 75¹⁸ ) : ( 5³⁶ × 3³⁶ ) = 9
( 3²⁰ × 15¹⁸ × 5¹⁸ ) : ( 5³⁶ × 3³⁶ ) = 9
( 15¹⁸ × 5¹⁸ ) : ( 5³⁶ × 3¹⁶ ) = 9
( 15¹⁸ ) : ( 5¹⁸ × 3¹⁶ ) = 9
( 3¹⁸ × 5¹⁸ ) : ( 5¹⁸ × 3¹⁶ ) = 9
3² = 9.
