Question

if P ^a is equal to Q ^ b is equal to r to the power c and pqr is equal to 1 then let us prove that 1/a+1/b+1/c=0​

Answer 1

Answer:

P = q^(b/a)

r= q^(b/c)

Now put the value of p and r in pqr=1

So the equation now becomes q^(b/a+b/c+1)= 1

So b/a+b/c+1= 0 ( as x^0= 1)

After rearranging we get 1/a+1/b+1/c =0
