Question

the side length of a square with an area of 19 square units is 19 square root. The 19 square roots is an irrational number between 4 and 5 explain why the value is between 4 and 5

Answer 1

`\text{We know}\ √(a)=b\ if\ b^2=a\\\\4 < √(19) < 5\ \text{because}\\\\4^2 < (√(19))^2 < 5^2\\\\16 < 19 < 25\to√(16) < √(19) < √(25)`
