The document discusses exponents and powers in mathematics. It defines key terms like base, exponent, and power. It provides examples of exponents like 22 = 4 (two squared) and 23 = 8 (two cubed). It notes rules for exponents like when the exponent is 1 the number is the same as the base, and when the exponent is 0 the answer is 1 except for when the base is 0. The document also discusses properties of exponents like product of powers, power to a power, power of product, and addition/multiplication of exponents.

1. PRESENTED BY GROUP 1 CLASS 8th "B" SUBJECT -MATHS

2. TOPIC EXPONENTS AND POWER

3. a number written as a base number with an exponent BASE EXPONENT LIKE THIS: 2 SAY 2 TO THE 5 th POWER POWER-

4. THE REPEATED FRACTION IN A MULTIPLICATON PROBLEM BASE = POWER FACTOR * FACTOR * FACTOR = PRODUCT 2 * 2 * 2 = 8 BASE -

5. THE NUMBER OF TIMES BASE IS MULTIPLIED BY ITSELF 2 2 {1 st time} * 2 {2 nd time} * 2 {3 rd time} = 40 EXPONENT-

7. POINTS TO REMEMBER

8. 2 SAY 2 TO THE 2 nd POWER OR TWO SQUARED MOST MATHEMATICIAN SAY TWO SQUARED 2 = 2 2 = 4 SQUARED= BASE 2

9. 2 SAY 2 TO THE 3 rd POWER OR TWO CUBED MOST MATHEMATICIANS SAY TWO CUBED 2 = 2 2 2 =8 CUBED = BASE 3

10. THE BASE IS ANY NUMBER BUT 0,THE ANSWER IS 1. 2 =1 4,638 =1 ANY NUMBER {except the number 0} =1 0 =UNDEFINED WHEN EXPONENT IS O !

11. THE ANSWER IS THE SAME NUMBER AS THE BASE NUMBER 2 =2 4,638 =4,638 ANY NUMBER =THE SAME BASE 0 =0 THE EXPONENT 1 IS USUALY INVISIBLE WHEN THE EXPONENT IS 1 !

12. Write out the original problem. Show the substitution with parentheses. Work out the problem. = 64 SUBSITUTION AND EVALUATING STEPS

13. PRODUCT OF POWERS POWER TO A POWER POWER OF PRODUCT ADD THE EXPONENTS MULTIPLY THE EXPONENTS MULTIPLICATION PROPERTIES

14. This property is used when dividing two or more exponential expressions with the same base. DIVISION PROPERTIES QUOTIENT OF POWER

15. Q1}Evaluate the variable expression when x = 1, y = 2, and w = -3 ? Step 1 Step 2 Step 3 Step 1 Step 2 Step 3 Step 1 Step 2 Step 3
