Question

Please tell what will be the answer​

Answer 1

Answer:

Step-by-step explanation:

10---irrational number

11----5/4 and 3/2

12---niether rccuring nor terminating

Answer 2

Answer:

10.

The number in the form of 2 + 3√2 is (b) irrational number.

Let a be a rational number (here 2) and b be a irrational number (here 3√2) then,

a + b, a - b, a * b and a / b are irrational numbers. (here the format is a + b)

11.

The 2 possible rational numbers between 1 and 2 is

a = 1 and b = 2

To find the mid term we use a + b / 2

1 + 2 / 2

3 / 2

One number is 3 / 2

Let a = 1 and b = 3/2

a + b / 2

1 + 3/2 / 2

2 + 3 / 2 / 2

5 / 2 * 2

5 / 4

Rational numbers between 1 and 2 is 3/2 and 5/4 which is option (C)

12.

The decimal form of an irrational number is (d) neither terminating nor recurring number.

Ex:

1. π = 3.14159265358979............ we can see that no number is recurring in an order or terminating.

2. √2 = 1.41421356237309......... we can see that no number is recurring in an order or terminating.

There are infinite number of irrational numbers.
