Question

Find the square root of the folowing by finding the unis and the tens digts (a) 324

Answer 1

√324


last digit is 4
we get 4 by 2 possible numbers

2²='4'
8²=6'4'

now cross last 2 digits of 324 remaining is 3
nearest square less than 3
1²<3<2²
so 1st digit will be "1 "( smaller is taken)
now 1*next number =1×2=2 and 2 is less then 3 means 3 is greater so we take greater digit i.e "8"

18 answer


mark me brainliest:)
