Question

find the square root by repeated subtraction of 343​

Answer 1

Step-by-step explanation:

Solution: This proceeds as:

Step 1: 9 - 1 = 8

Step 2: 8 - 3 = 5

Step 3: 5 - 5 = 0

As you can see that given number 9 was repeatedly subtracted by successive odd numbers (starting from 1) and we get zero in third step.

Therefore 3 is the square root of 9

Or we can also write it as:

√� 9 � = 3

Answer 2

Answer:

$\sqrt{343} \: = \: \sqrt{49 \: \times \: 7}$

$= \: 7 \sqrt{7}$
