Answer 4

Let me ask this, do you know what an irrational number is?

Answer 5

an irrational number is a real number that cannot be expressed as a ratio of integers

Answer 6

can't be written as a fraction ..... is it c?

Answer 7

Good! So for question 1, we need to use a calculator and take the square root of 13 to find the decimal approximation.
sqrt(13)=3.605
So yes, for question 1 the correct answer would be C

Answer 8

and the second is a?

Answer 9

Yes, the correct answer is A. You can move the decimal place to the right one and make it become 9.5 *10^7

Answer 10

and the third http://prnt.sc/cixrtc

Answer 11

is c too?

Answer 12

C is a rational number because it is a fraction (a ratio)

Answer 13

So the square root of 9 is 3 correct?

Answer 14

are you sure? is it b?

Answer 15

Which makes sqrt(9) a rational number as well.

Answer 16

The only answer that is not rational is B. Sqrt(5) is not a perfect square, and only has a decimal approximation.

Answer 17

So the final answer for Q3 is B.
