Evaluate square root of 39
Problem
Solution
Identify the number under the radical, which is
39 Check for perfect square factors. The factors of
39 are1 , 3, 13, 39.N*o*n*e*o*ƒ*t*h*e*s(e)*ƒ*a*c*t*o*r*s,o*t*h*e*r*t*h*a*n $, are perfect squares.Conclude that the square root cannot be simplified into a simpler radical form involving integers.
Estimate the value if a decimal approximation is needed. Since
6=36 and7=49 the value is between6 and7 Calculate the decimal approximation using a calculator for higher precision.
