Question
Express the following fraction in simplest form, only using positive exponents.start fraction, left parenthesis, minus, 4, u, to the power minus 5 , right parenthesis, cubed, divided by, minus, 5, u, to the power minus 6 , end fraction−5u −6 (−4u −5 ) 3 Answer
Solution
Claro, vamos a resolver el problema paso a paso.
Primero, simplifiquemos la expresión dentro del paréntesis y luego apliquemos la potencia:
Cuando elevamos un producto a una potencia, elevamos cada factor a esa potencia:
Calculamos cada parte por separado:
Entonces, la expresión se convierte en:
Ahora, dividimos esta expresión por el denominador original:
Dividimos los coeficientes y restamos los exponentes de las mismas bases:
Para los exponentes de :
Entonces, la fracción simplificada es:
Finalmente, para expresar la respuesta con exponentes positivos, recordamos que :
Por lo tanto, la fracción en su forma más simple, usando solo exponentes positivos, es:
