(A) Let the missing value be $x$.$\sqrt{x 	imes 7} 	imes 18 = 84$Divide both sides by $18$:$\sqrt{x 	imes 7} = \frac{84}{18} = \frac{14}{3}$Square both sides to remove the square root:$x 	imes 7 = \left(\frac{14}{3}ight)^2$$x 	imes 7 = \frac{196}{9}$Solve for $x$:$x = \frac{196}{9 	imes 7}$$x = \frac{196}{63}$$x = \frac{28}{9} \approx 3.111...$Rounding to two decimal places,we get $x = 3.11$.

$\sqrt{? \times 7} \times 18 = 84$
