Answer:
2.23
Explanation:
first, what does square root means? it means a number which produces a specified quantity when multiplied by itself.
so in this suation we need to find a number that is multiplied by itself to get 5.
5 does not have a square root in whole numbers it has a square root in decimal. we need to find the closest number to 5 that has a square root and that is a 4. the square root of 4 is 2 so, the 5 square root is gonna be 2 and something decimal.
lets multiply :
2.25*2.25 = 5.0625
the number 5.0635 is a little too big for the number 5
now lets multiply :
2.23*2.23 = 4.9729
if we round the number 4.9729 it will equal 5
so, the square root of 5 is 2.23
Have a wonderful day
