Find the square root of 16 by the repeated subtract method.

$\huge{\star{\mathfrak{\underline{\underline{\red{Answer:-}}}}}}$

$\sf{Step\:1: 16-1=15}$

$\sf{Step\:2: 15-3=13}$

$\sf{Step\:3: 12-5=7}$

$\sf{Step\:4: 7-7=0}$

We have subtracted from 16, the successive odd numbers from 1 to 7 and obtained 0 in step 4.
