Question 2

Find the value of x. if $$\sqrt{1-\frac{x}{324}}=\frac{13}{18}$$

Solution

Expression : $$\sqrt{1-\frac{x}{324}}=\frac{13}{18}$$

=> $$\sqrt{\frac{324-x}{324}}=\frac{13}{18}$$

=> $$\frac{324-x}{324}=(\frac{13}{18})^2$$

=> $$\frac{324-x}{324}=\frac{169}{324}$$

=> $$324-x=169$$

=> $$x=324-169=155$$

=> Ans - (A)
