1) y = 2x⁵ - x
y' = 2(x⁵)' - x' = 10x⁴ - 1
2) y = - 3Sinx + 2Cosx
y' = - 3(Sinx)' + 2(Cosx)' = - 3Cosx - 2Sonx
3) y = 2/3x³ - x² - 7x
y' = 2/3(x³)' - (x²)' - 7(x)' = 2/3 * 3x² - 2x - 7 = 2x² - 2x - 7
4) y = (x + 2)(x² - 7x + 5)
y' = (x + 2)' * (x² - 7x + 5) + (x + 2)(x² - 7x + 5)' = 1 * (x² - 7x + 5) +
+ (x + 2)(2x - 7) = x² - 7x + 5 + 2x² - 7x + 4x - 14 = 3x² - 10x - 9
5) y = x² Sinx
y' = (x² )' * Sinx + x² * (Sinx)' = 2xSinx + x²Cosx
6) y = (3x - 5)⁶
y' = [(3x - 5)⁶]' = 6(3x - 5)⁵ * (3x - 5)' = 18(3x - 5)⁵

Объяснение:
247/2,23= 24700/223= 110 170/223 = 110,76233
log0.08(2.5*√2)=log8/100(25/10*2^1/2)=log2/25(5*2^-1 *2^1/2)=log2/5^2(5*2^-1/2)=1/2log√2/5(5/√2)= -1/2log5/√2(5/√2)= -1/2= -0.5
Правильно нет не знаю но вот,
15х2-5х+4-15х2=17
-5х+4=17
-5х=17-4
-5х=13
х=-13\5=-2,6
