(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
(27^3 / 125^6)^2/9 = (3^9 / 25^9)^2/9 = ((3/25 )^9)^2/9 = (3/25)^2 = 0.12^2 =
= 0.0144
1)
5x = 12.5
x = 2.5
2)
2x = 5
x = 2.5
3)
4x - 7x + 2 = 17
-3x = 15
x = -5
5000/100 = 50 (1%)
5000-50*10 = 4500
4500/100 = 45(1%)
4500-45*10 = 4050
Ответ: 4050
