1. 1.) India was the first country to enter Mars’ orbit on their first attempt. THIS HAPPENED TODAY!! India spent $74 million the film Gravitycost $100 million to make U.S. spent $671 million 1.) Write each number in standard form. 2.) Find the cost difference of the U.S. and India of this expedition. 3.) How many times more did the U.S. spend than India? Round to the nearest hundredth.

2. Do Now Solve. Round to the nearest hundred if necessary 1.) 10.15 ÷ 5.2 2.) 4.09 ÷ 0.02 1.95 204.5

3. 9/24/2014 1-3 A Exponents

4. Exponent- tells how many times a number called the base is used as a factor Example- 83 8is the base 3is the exponent

5. 83 The eight is a factor three times 8 × 8 × 8 = 512  83 = 512 83 ≠ 8 × 3  WRONG!!!!

6. Special Exponents Zero Exponents- any number raised to the 0 power = 1 510 = 1

7. Write each product using exponential form. 1.) 2 × 2 × 2 2.) 8 × 8 × 8 × 8 × 8 85 23

8. Write each power as a product of the same number. Then find its value 3.) 27 27=2 × 2 × 2 × 2 × 2 × 2 × 2 =128

9. Find the value 4.) 64 64=6 × 6 × 6 × 6 =1,296

10. Exit Ticket

11. Write each product using an exponent. 1.) 5 × 5 × 5 × 5 2.) 3 × 3 × 3 × 3 × 3 Write each power as a product of the same number. Then find its value. 3.) 264.) 45 5.) 1,0010
