Question

el ejercicio que dice 2

Answer 1

Respuesta:

8

Explicación paso a paso:

Por dato tenemos:

(3/5)^(15/12) = (3/5)^x

A bases iguales exponentes iguales:

15/12 = x

(- 8/125)^(5/3) = (-8/125)^y

A bases iguales exponentes iguales:

5/3 = y

Hallamos:

= 16^(x/y)

= 16^ [(15/12) / (5/3)]

= 16^ (3/4)

= (2^4)^(3/4)

= 2^(4*3/4)

= 2^(3)

= 8

Answer 2

.....(1)

12/15 x

(3/5) = (3/5)

5/4 x

(3/5) = (3/5)

x=5/4

....(2)

5/3 y

(-8/125) = (-8/125)

y =5/3

x/y

(16) = 8
