we have to find :-
√169/14×17/√289×78/√169 = ?

solution:-
we know that :
13² = 169 , 17² = 289 

here,
(√169/14)×(17/√289)×(78/√169) 
= (13 / 14) × (17 / 17) × (78 / 13) 
=(13 / 14) × (78 / 13 )
=78 / 14

Answer 2

Hello my friend, firstly, thank you for posting this question to Brainly team. We are glad to answer it in the most easiest method.

$\sqrt{169} = 13 \\ \sqrt{289} = 17$
Hope you are aware/clear about these sqrt values of 169 and 289 as mentioned above.

Now, this problem is simplified as follows:

√169/14×17/√289×78/√169

= (13/14) x (17/17) x (78/13)

= 78/14 (After canceling the like terms 13 and 17 in the above step)
