Question 9a)

We want to rewrite

as a regular number.

The given notation is called the scientific notation.

In this format, the number is written in the form k×10ⁿ where 0<k<1 and n is an integer.

To convert to standard notation format we multiply k repeatedly by 10, n-times.

This implies that:

Question 9b)

Question 9c)

Question 9d)

Question 10a)

To find the square root of a perfect square, we look for a number that multiplies itself to give the number in question.

For we have 4×4=16[/tex]

This implies that:

Question 10b)

Also 13×13=169

This implies that;

Question 10c)

Again 8×8=64

This my that:

Question 10 d)

Finally, 20×20=400

Therefore

50- 250 is correct i did that one too
