None of these are correct

The value x = 35 is correct

Explanation:

Step(i):-

Given

We will apply logarithmic formula

log(a) + log (b) = log a b

  logₓ a = b

⇒   a = xᵇ

Step(ii):-

⇒  2 ( x + 15 ) = 10²

⇒ 2 x + 30 = 100

⇒  2 x = 70

⇒  x = 35

Final -

x = 35

Verification:-

log x ⁿ = n log x

2 log¹⁰ ₁₀     = 2

2 =  2       (  log¹⁰ ₁₀ = 1

replace   c   with   a   and simplify.

a = c , b = a, q = n , 2 , a = c , 900 b= a , 700 , q = n , 600 , 2 = b o t h , b = a , q = n
