how to solve this?

Question

solve the equation for the given number
L=2b^2/a ;a
show process please

i need to see if i did it right

Answer 1

From your question, this is what I am interpreting:

Solve the equation for 'a': L = (2b^2)/a

If this is the case, this is how you do it.

First, multiply both sides by a:
a*L = 2b^2

Then divide both sides by L to isolate a:
a = (2b^2)//L

---------

Hope this helps

Answer 2

you need to explain a lot of this, is this L=2b^(2/a) or L=(2b^2)/2a or even possibly L=2(b^2)/a? What does the ";a" mean? Does that mean in terms of a? Do you know how to differentiate/take the derivative?
