Step-by-step explanation:

hopefully you will understand

Answer 2

The answers of the given questions are as follows -

• Given,

The numbers are = 5,9,12,16,50,60,64,72,80,81

To find,

The square numbers.

Solution,

The square numbers are :

9 = (3)² , 16 = (4)² , 64 = (8)² , 81 = (9)²

Hence, the square numbers are 9,16,64,81

• Given,

The numbers are = 3,6,8,9,12,15,16,20,21,42

To find,

The triangular numbers

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Triangular numbers are :

3 (two rowed triangle), 6 (three rowed triangle), 15 (five rowed triangle), 21 (six rowed triangle).

Hence, the triangular numbers are 3,6,15,21

• Given,

The number is both square and triangular.

To find,

The value of the number.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

36 = (6)² = a square number

36 = triangular number = eight rowed triangle

Hence, 36 is both square and triangular.

• Given,

First square number = 4

To find,

Tenth square number.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First square number = 4

First square rooted number = √4 = 2

Tenth square rooted number = 2+9 = 11

Tenth square number = (11)² = 121

Hence, the tenth square number = 121

• Given,

First triangular number = 3

To find,

Tenth triangular number.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First triangular number = 3 = two rowed triangle

Tenth triangle = 2+9 = 11 rowed

Tenth triangular number = (11+10+9...+1) = 66

Hence, the tenth triangular number is 66
