1. x = 6
2. x = 2.5
3. x = 2; x = 3
(14·2⁷·10¹⁷ - 24·2²²·5¹⁷)/(6²·2²⁵·5¹⁶ - 20¹⁴·100) = (7·2⁸·10¹⁷ - 3·2²⁵·5¹⁷)/(3²·2²⁷·5¹⁶ - 2²⁸·5¹⁴·2²·5²) = 2²⁵·5¹⁷·(7 - 3)/(3²·2²⁷·5¹⁶ - 2³⁰·5¹⁶) = 2²⁷·5¹⁷/(2²⁷·5¹⁶·(3² - 2³)) = 5
Ответ:
-40.
Объяснение:
-13 1/3*1 7/23-13 1/3*1 16/23 = -13 1\3(1 7\23+1 16\23)=-13 1\3 * 3 = -40\3 * 3 = -40.
