Estimates are used to get the approximated value of an expression.
- The estimate of [tex]d^2 = 54[/tex] is 7
- The actual value is: 7.34846923
The equation is given as:
[tex]d^2 = 54[/tex]
The perfect closest to 54 is: 49
So, the equation becomes
[tex]d^2 \approx 49[/tex]
Take square of both sides
[tex]d \approx \sqrt{49[/tex]
[tex]d \approx 7[/tex]
The actual value is calculated as follows:
[tex]d^2 = 54[/tex]
Take square roots
[tex]d = \sqrt{54[/tex]
[tex]d = 7.34846923[/tex]
Hence, the estimate is less than the actual value
