Solve for x : 2 log x + 1 = log 250

Question

KnowledgeBoat · Accepted Answer

Given, ⇒ 2 log x + 1 = log 250 ⇒ log x2 + log 10 = log 250 ⇒ log (10 × x2) = log 250 ⇒ (10 × x2) = 250 ⇒ x2 = ⇒ x2 = 25 ⇒ x = ⇒ x = 5. x cannot be equal to -5 as the argument of a logarithm cannot be negative. Hence, the value of x = 5.
