Hope uh understand and mark as brainilist

Answer 2

Step-by-step explanation:    3✓15 / 15✓5

= 3√15/15√5 × √5/√5

= √5(3√15)/15(√5²)

= √5(3√15)/15×5

= √5(3√15)/75 ------- ANS.

HERE WE DID NOT SIMPLIFY THE NUMERATOR BECAUSE IF WE LEAVE IT LIKE I LEFT, IT WILL LOOK LIKE I HAVE TAKEN COMMON.

AND WHILE RATIONALIZING , I MULTIPLIED ONLY √5/√5 BECAUSE , IF WE MULTIPLIED  15√5/15√5 THE CALCULATION WOULD BE A LITTLE TOUGH AND WILL TAKE TIME

HOPE IT HELPS YOU
