Worked practice questions
Between which two consecutive integers does sqrt 50 lie?
- 6 and 7
- 7 and 8
- 8 and 9
- 5 and 6
Show answer and solution
Correct answer: B. 7 and 8
49 < 50 < 64, so the root lies between 7 and 8.
In Heron's method for the root of a, the estimate x is replaced by what?
- (x - a/x) / 2
- (x + a/x) / 2
- (x + a) / 2x
- 2x + a/x
Show answer and solution
Correct answer: B. (x + a/x) / 2
The Babylonian iteration is x(n+1) = (x(n) + a/x(n)) / 2, the average of x and a/x.
