Assessment: WAEC SSCE - General Mathematics - 2005 (Objective) Subject: General Mathematics

Question 1 Report

If \(log_9x= 1.5\),find x
Answer Details
We can rewrite the equation in exponential form as follows: $$9^{1.5} = x$$ Using the exponent rules, we can simplify $9^{1.5}$ as: $$9^{1.5} = \sqrt{9^3} = 3^3 = 27$$ Therefore, $x = 27$. So the correct option is (B) 27.
