### Square and Cube Roots

1.Find the Square Root of 0.0025
Square Root of 0.0025
=Square Root of 25/10000
=Square Root of (5*5)/(2*2*2*2*5*5*5*5)
=5/(2*2*5*5)
=5/100
=0.05

2.Find the Cube Root of 0.729
Cube Root of 0.729
=Cube Root of 729/1000
=Cube Root of 9*9*9/10*10*10
=9/10
=0.9

3.Find the Cube Root of 8/0.125
Cube Root of 8/0.125
=Cube Root of 8000/125
=Cube Root of (2*2*5)x(2*2*5)x(2*2*5)/(5*5*5)
=20/5
=4

1. Feel free to post questions here and i will try my best to help you :D

2. Feedback on Question 1:

The steps are clear.
You could explain further on the thinking behind the following steps:
"=Square Root of 25/10000
=Square Root of (5*5)/(2*2*2*2*5*5*5*5)
=5/(2*2*5*5)"

That is, using the mathematics vocabulary like factorise and grouping.

3. Feedback on Question 2:

The working is clear except that "10" was missing in the 3rd line of the working.

Similarly, the thinking behind the working was not articulated.

4. Feedback on Question 3:

Working is clear, except that the thinking behind the steps were not articulated.
