Question

6) (3/4 -0, 5) ² - (1 - 3/7 × 1 3/4) ²+3 1/2×3/28​

Answer 1

Пошаговое объяснение:

1) (3/4 - 0,5)² = (0,75 - 0,5)² = 0,25² = 0,0625

2) (1 - 3/7 * 1 3/4)² = (1 - 3/7 * 7/4)² = (1 - 3/4)² = (1/4)² = 1/16 = 0,0625

3) 3 1/2 * 3/28 = 7/2 * 3/28 = 1/2 * 3/4 = 3/8 = 0,375

4) 0,0625 - 0,0625 + 3/8 = 3/8 или 0,375
