If log10 x = a, the value of 10^a - 1 in terms of x is : 1. 10x 2. x/10 3. 10/x 4. 1/10x

Question

KnowledgeBoat · Accepted Answer

Given, ⇒ log₁₀ x = a ⇒ x = 10^a .......(1) We need to find the value of: ⇒ 10^{a - 1} ⇒ 10^a.10^-1 Substituting value of 10^a from equation (1), in above equation, we get : ⇒ x.10^-1 ⇒ . Hence, Option 2 is the correct option.
