Question

resuelve cada expresión utilizando el cubo de un binomio (3/5X-5)3​

Answer 1

Respuesta:

((3/5)x-(5)) ³ = 27/125x³+2423/125

((3/5)x-(5)) ³

= ((3/5) ³(x) ³ -3(3/5)²(5)+3(3/5)(5)²+(3/5)³)

= (27/125)(x)³-3(9/25)(5)+3(3/5)(25)+27/125 )

= (27/125)x³-(27/25)×5+9/5×25+27/125

= 27/125x³-135/25+(225/9)+27/125

= 27/125x³-(27/5)+25-(27/125) ; 25 = 125/5

= 27/125x³+((-27/5)+(125/5))-27/125

= 27/125x³+98/5-27/125

= 27/125x³+(98/5-27/125)

= 27/125x³+2423/125
