1.) India was the first country to enter Mars’ orbit on their first attemptIndia spent $74 million the film Gravity cost $100 million to makeU.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.

Welcome Activity

Solve. Round to the nearest hundred if necessary

1.) 10.15 ÷ 5.2

2.) 4.09 ÷ 0.02

10/7/2015 1-3 A Exponents

Exponent- tells how many times a number called the base is used as a factor

Example- 83

8 is the base

3 is the exponent

83

The eight is a factor three times8 × 8 × 8 = 512 83 = 512

83 ≠ 8 × 3 WRONG!!!!

Special Exponents

Zero Exponents- any number raised to the 0 power = 1

510 = 1

Write each product using exponential form.

1.) 2 × 2 × 2 2.) 8 × 8 × 8 × 8 × 8

23 85

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

Find the value

4.) 64

64= 6 × 6 × 6 × 6

= 1,296

Your TurnWrite 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.) 26 4.) 45

5.) 1,0010
