Exponents- An exponent refers to a number that how many times to use the number in a mathematical operation like multiplication, division etc. 
Exponents is also termed as power. 
Power- An expression that represents repeated multiplication of the same number is called a power.
Special cases when the exponent is 0 or 1 :-
Case 1.  When the power is 0
a^0 = 1
67^0 = 1
Case 2. When the power is 1 
a^1 = a
9^1 = 9
                    Laws of Exponents
The following identities hold for all integer exponents :-

Practice Questions:-
1.Find out the value of (2/5)3 ? 
 2.What is the power of a number when squared?
3. Simplify: (3/2)2 + (2/3)2 + (5/4)2
4. If 4x = 64, then 32x = ?
5. Divide x5 by x2

          SQUARES AND SQUARE ROOTS   Square number - The square of a number is the product of the number with the number itself.  A given number is a perfect square if its prime factors can be expressed in pairs of equal factors.  A perfect square number is never negative. For example - 8^2 = (8×8) = 64 Facts About Squares -  1. A number ending in 2, 3, 7 or 8 is never a perfect square.  2. A number ending in an odd number of zeros is never a perfect square.  3. The square of an even number is always even.  4. The square of an odd number is always odd.  5. The ending digits of a square number is 0, 1, 4, 5, 6, or 9 only.  Note:- It is not necessary that all numbers ending with digits 0, 1, 4, 5, 6, or 9 are square numbers.  Important Facts-  1. Numbers ending in an even number of zeros are not necessarily perfect squares. Eg- 3700, 290000, 47000000.   Practice Questions :-  1. Find the square of 54 ?  2. What least number must be added to 5607 to mak
