Answer 1

,, here it is......

Answer 2

Answer:

The required number to make 700 a perfect square is 7.

Step-by-step explanation:

First of all, taking L.C.M of the given number 700 to achieve smallest number.

700 = 2*2*5*5*7

So after calculating the L.C.M of 700, we've noticed that 2 & 5 are in pairs and the number 7 is the only unpaired number. So multiplying the number 700 with 7, we'll get;

700*7 = 2*2*3*3*7*7

4900 = 2*2*3*3*7*7

which is a perfect square.
