Answer 2

Hello user !!!

Your answer :-

From 1st figure ,
Given :-
First number :- 64 .
second :- 5
Third :- 40
If we do something do 1st and 2nd only we will get third one right !
So , observe the trick followed here :-

root 64 = 8

When we mutiply 8 × 5 = 40

So they are using square roots.

Let's justify for second one too ...

Given ,
First number :-81
Second number :-7
Third number :-63

Root 81 = 9
→9 × 7 = 63.

Tada see we got it .

Let's apply this too Third figure too...

Given,
First number :- 16
Second number :- 4
Third = ?
Let's find second one.

Root 16 = 4

→4 × 4 = 16.

Hence the missing number is 16.

Formula used :-
Root of first number × Second number =Third number.

Hope it helps you ^_^
