The correct answer is: w= ch^2/ 600
Use the rule ; a/b x c= ac/ b
C= 600ww/h^2
Use product rule ; x^a x^b= x^a+b
Multiple both side by h^2
Ch^2=600w^2
Divide both side by 600
Ch^2 /600 =w^2
Square root /ch^2 / 600= w
Now take the square root of both side
W= ch^2/ 600
Sorry I am not sure but I think it’s the last one
