(D) Given the equation: $\left(\frac{x}{15}\right)\left(\frac{x}{135}\right) = 1$Multiply the numerators and denominators: $\frac{x^2}{15 \times 135} = 1$$x^2 = 15 \times 135$$x^2 = 15 \times (15 \times 9)$$x^2 = 15^2 \times 3^2$Taking the square root on both sides: $x = \sqrt{15^2 \times 3^2}$$x = 15 \times 3 = 45$Therefore,the value of $x$ is $45$.
