√4.5 * √72 = √4.5 *√ 9*8 = √4.5 * 3 * √8 = √4.5 * 3 * √4*2 = √4.5 * 3 * 2 * √2 = √4.5 * 6 * √2 = √4.5*√2 * 6 = √9 * 6 = 3*6 = 18
т.к выглядит по татарски , напишу письменно
корень их 4,5 умножим на корень из 72 , разложим 72 на множители- 9 и 8( что бы корень исчез)  , корень из 9 - это 3 , следовательно получаем:
корень из √4.5 * 3 * √8 . 8 тоже можно разложить на множители - это 4*2
а корень из 4 - это 2,
получаем корень из 4,5, умноженное на 3, умноженное на на 2  и ещё раз умноженное на корень из двух
3 и 2 перемножаем , получаем 6.
и теперь у нас остаётся корень из 4,5 и корень из двух
их мы тоже перемножим , получим корень из 9
а корень из 9 - это 3
получается что 6*3=18
