1156 = 2 x 578

= 2 x 2 x 289

= 2 x 2 x 17 x 17

∴ √1156 = √( 2 x 2 x 17 x 17 )

√1156 = 2 x 17

√1156 = = 34

529 = (23 x 23)

√529 = 23

Perimeter of square = 4 (side)

100 = 4(side)

side = 100/4 = 25 cm

Area of square = (side)^{2} = (25)^{2} = 625 sq. cm

Perimeter of rectangle = 2(l +b)

100 = 2 (l +b)

l + b = 100/2 = 50

The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. Every rational number can be written as a fraction a/b, where a and b are integers. If a number is an integer, it must also be a rational.

A rhombus is a type of quadrilateral. It is a special case of a parallelogram, whose diagonals intersects each other at 90 degrees. This is the basic property of rhombus. The shape of a rhombus is in a diamond shape, hence it is also called a diamond.

Some of the important properties of the rhombus are as follows:

- All sides of the rhombus are equal.
- The opposite sides of a rhombus are parallel.
- Opposite angles of a rhombus are equal.
- In a rhombus, diagonals bisecting each other at right angles.
- Diagonals bisect the angles of a rhombus.
- The sum of two adjacent angles is equal to 180 degrees.
- The two diagonals of a rhombus form four right-angled triangles which are congruent to each other
- You will get a rectangle when you join the midpoint of the sides.
- You will get another rhombus when you join the midpoints of half the diagonal.
- Around a rhombus, there can be no circumscribing circle.

As discussed earlier, there are majorly six laws or rules defined for exponents. In the table below, all the laws are represented.

- a
^{m}.a^{n}=a^{m+n} - (a
^{m})^{n}= a^{mn} - (ab)
^{n}= a^{n}b^{n} - (a/b)
^{n}= a^{n}/b^{n} - a
^{m}/a^{n}= a^{m-n} - a
^{m}/a^{n}= 1/a^{n-m}
