( x + 4 )² + ( 3 - x )( 3 + x ) = x² + 8x + 16 + 9 - x² = 8x + 25
x = - 1,1
8 * ( - 1,1 ) + 25 = - 8,8 + 25 = 16,2
Ответ 16,2
-------------------
( 2 ⁴ )⁵ = 2 ²°
8² = ( 2³ )² = 2⁶
2²° * 2⁶ = 2²⁶
2²⁶ : 2²³ = 2³ = 8
Ответ 8
У = 11 +24х -2х√х = 11 +24х -2х*х^1/2 = 11 +24х -2х^3/2
y' = 24 - 2*3/2x^1/2 = 24 -3√x
6-3а=5х-4х
3(2-а)=х
а=1, 0, -1, -2 и т.д.
