199. 1) (0, 25) ^ 9 * (- 4) ^ 9

3) 4) (6/11) ^ 3 * (8, 5) ^ 3 (1/9) ^ 5 * (4, 5) ^ 5 2) (- 2/7) ^ 7 * (- 3, 5) ^ 7

Answer 1

Объяснение:

1. (-0,25)⁹(-4)⁹

-0,25⁹×(-4)⁹

0,25⁹×4⁹

(0,25×4)⁹

1⁹ = 1

2. (-2/7)⁷×(-3,5)⁷

-(2/7)⁷×(-3,5⁷)

2/7⁷×3,5⁷

(2/7×3,5)⁷

1⁷ = 1

3. (6/11)³×(8,5)³

(6/11×8,5)³

(6/11×17/2)³

(3/11×17)³

(51/11)³ = 2601/121

4. (1/9)⁵×(4,5)⁵

(1/9×4,5)⁵

(1/9×9/2)⁵

(1/2)⁵ = 1/32
