What two positive real numbers whose product is have the smallest possible​ sum?
alexandr402 [8]

Answer:

En matemáticas, el conjunto de los números reales (denotado por {\displaystyle \mathbb {R} }\mathbb{R}) incluye tanto a los números racionales, (positivos, negativos y el cero) como a los números irracionales;1​ y en otro enfoque, trascendentes y algebraicos. Los irracionales y los trascendentes2​ (1970) no se pueden expresar mediante una fracción de dos enteros con denominador no nulo; tienen infinitas cifras decimales aperiódicas, tales como: {\displaystyle {\sqrt {5}}}{\sqrt  {5}}, π, o el número real: {\displaystyle log(2)}{\displaystyle log(2)}, cuya trascendencia fue enunciada por Euler en el siglo XVIII.2​

Los números reales pueden ser descritos y construidos de varias formas, algunas simples aunque carentes del rigor necesario para los propósitos formales de matemáticas y otras más complejas pero con el rigor necesario para el trabajo matemático formal.

Durante los siglos XVI y XVII el cálculo avanzó mucho aunque carecía de una base rigurosa, puesto que en el momento prescindían del rigor y fundamento lógico, tan exigente en los enfoques teóricos de la actualidad, y se usaban expresiones como «pequeño», «límite», «se acerca» sin una definición precisa. Esto llevó a una serie de paradojas y problemas lógicos que hicieron evidente la necesidad de crear una base rigurosa para la matemática, la cual consistió de definiciones formales y rigurosas (aunque ciertamente técnicas) del concepto de número real.3​ En una sección posterior se describirán dos de las definiciones precisas más usuales actualmente: clases de equivalencia de sucesiones de Cauchy de números racionales y cortaduras de Dedekind.

The equation 24x2+25x−47ax−2=−8x−3−53ax−2 is true for all values of x≠2a, where a is a constant.
eimsori [14]

Answer:

Option B is correct

Explanation:

Value of a is -3

Given the equation:   \frac{24x^2+25x-47}{ax-2} =-8x-3-\frac{53}{ax-2} is true for all x\neq 2a

To find the value of a.

Multiply both sides of the given equation by (ax-2), we have;

 24x^2+25x-47=(-8x-3)(ax-2)-53

Using FOIL Method to multiply two binomials i.e (-8x-3)(ax-2)

24x^2+25x-47=-8ax^2+16x-3ax+6-53

or

24x^2+25x-47=-8ax^2+x(16-3a)-47

Since the coefficients of the x^2 term have to be equal on both sides of the equation. we have;

-8a = 24

Divide both sides by -8 we get;

a = -3

Therefore, the value of a is, -3
