Answers

Answer:

Proof of [tex]\dfrac{1}{z}}=\dfrac{1}{y}+\dfrac{2}{x}[/tex]  is shown below.

Explanation:

The given equation is

[tex]2^x=3^y=12^z[/tex]

To prove : [tex]\dfrac{1}{z}=\dfrac{1}{y}+\dfrac{2}{x}[/tex]

Proof : Let as assume,

[tex]2^x=3^y=12^z=k[/tex]

[tex]2^x=k\Rightarrow 2=k^{\frac{1}{x}}[/tex]    ...(1)

[tex]3^y=k\Rightarrow 3=k^{\frac{1}{y}}[/tex]      ...(2)

[tex]12^z=k\Rightarrow 12=k^{\frac{1}{z}}[/tex]    ...(3)

We know that

[tex]12=2\times 2\times 3[/tex]

[tex]12=(2)^2\times 3[/tex]

Using (1), (2) and (3), we get

[tex]k^{\frac{1}{z}}=(k^{\frac{1}{x}})^2\times k^{\frac{1}{y}}[/tex]

[tex]k^{\frac{1}{z}}=k^{\frac{2}{x}}\times k^{\frac{1}{y}}[/tex]

[tex]k^{\frac{1}{z}}=k^{\frac{2}{x}+\frac{1}{y}}[/tex]

On comparing both sides, we get

[tex]\dfrac{1}{z}}=\dfrac{2}{x}+\dfrac{1}{y}[/tex]

[tex]\dfrac{1}{z}}=\dfrac{1}{y}+\dfrac{2}{x}[/tex]

Hence proved.

Perception can be defined as the set of processes and activities related to the stimulation that reaches the senses, through which we obtain information regarding our habitat, the actions we carry out in it and our own internal states. Weber's law states that the increase in the intensity of the stimulus necessary to provoke a change in sensation is proportional to the intensity of the initial stimulus, that is, the stronger the initial stimulus is, the greater the additional intensity required for the second stimulus to be perceived as different.
