[HW] Workbook Chap 1 Review Exercise 1 (p15-p17) - 2 Questions of your choice

This is an exercise to consolidate what you learnt in this chapter (to-date).

Pace yourself to do these questions in the workbook.
It may take up to 2 hours if you were to complete the entire exercise.

Advice: Review and revise what you learnt in this topic (go through the notes) and blog posts. 

As a contributing member of the class, you will submit answers to 2 questions (your choice) to the padlet before next MONDAY (27 Jan). With this, we can learn from each other how we approach certain questions and present our answers. You may also ask questions or provide feedback to your peers. (remember to observe 4Rs here).

Feedback will be provided to you after the public holidays.

Challenging Question: Roots

Submitted on behalf of FELIX ZHU SING HAN 


[Checked: 21 Jan 2020]
Working needs greater clarity - need to show how you systematically work from the given number.

Challenging Question: Roots

[Checked: 21 Jan 2020]

Should not apply estimation as it will introduce greater error margin.

The method is you take the last digit of the number, 9870

Which is 0

Then ignore the last 3 numbers.

Which leads us to number 9.

The closest cube number is 8.

The root of 8 is 2

Put 2 in front of 0, which was the last digit of 9870.

Thus the answer is 20

(estimated)
