Answer:
None of these are correct
The value x = 35 is correct
Explanation:
<u><em>Step(i):</em></u>-
Given
We will apply logarithmic formula
log(a) + log (b) = log a b
logₓ a = b
⇒ a = xᵇ
<u><em>Step(ii)</em></u>:-
⇒ 2 ( x + 15 ) = 10²
⇒ 2 x + 30 = 100
⇒ 2 x = 70
⇒ x = 35
<u><em>Final answer:-</em></u>
x = 35
<u><em>Verification:-</em></u>
<u><em></em></u>
log x ⁿ = n log x
2 log¹⁰ ₁₀ = 2
2 = 2 ( log¹⁰ ₁₀ = 1
