There is an obvious solution; do you see it?How to calculate the value of b, if the equation is 1/T^2=1/T^b?

But were you told the value of T, or what its possible values are? (If T were 1, everything would change!)

What have you tried? where are you stuck? It is hard to help you if you do not tell us where you are stuck.How to calculate the value of b, if the equation is 1/T^2=1/T^b?

I'll try to start you off. On both sides of the equal sign you are dividing 1 by different expressions (T^2 and T^b). What do you think must be true of the two expressions (are their sum 17, is their difference 11, are they equal to one another....?)

Do you see that if 1/x= 1/y then x= y? If that not obvious multiply both sides of 1/x= 1/y by xy.

1/T^2 = 1/T^b

or, T^b = T^2

or, b = 2

1/x X xy = 1/y X xyDo you see that if 1/x= 1/y then x= y? If that not obvious multiply both sides of 1/x= 1/y by xy.

or, y = x, still I don't understand how to find the value of b if the equation is 1/T^2 = 1/T^b

Yes, that is correct.Do you mean to say

1/T^2 = 1/T^b

or, T^b = T^2

or, b = 2

In your example, x= T^2 and y= T^b. so (1/T^2)(T^2T^b)= (1/T^b)(T^2T^b) which give T^b= T^2.1/x X xy = 1/y X xy

or, y = x, still I don't understand how to find the value of b if the equation is 1/T^2 = 1/T^b

As you saw in your previous post that gives b= 2.

If you erased the b in your problem what would you replace it with so both sides look exactly the same. The answer is 2, so yes b = 2.Do you mean to say

1/T^2 = 1/T^b

or, T^b = T^2

or, b = 2
