express each of the following numbers using exponential notation (a) 1

1.	express each of the following numbers using exponential notation (a) 12500 (b) 27000 (c) -343 (d) 62500
Answer» a) 12500 = 10,000 + 2000 + 500 = 1 x 10 power 4 + 2 x 10³ + 5 x 10² B ) 27000 = 20000 + 7000 = 2 x 10 POWER4 + 7 x 10 ³ c ) -343 = - 300 - 40 - 3 = -3 x 100 - 4 x 10 - 3 x 1 = - 3 x 10² - 4 x 10 - 3 x 1 d) 62500 60,000+2000+500 = 6X 10 power 4+2x 10³ +5 x 10²

express each of the following numbers using exponential notation (a) 12500 (b) 27000 (c) -343 (d) 62500

Answer»

a) 12500

= 10,000 + 2000 + 500

= 1 x 10 power 4 + 2 x 10³ + 5 x 10²

B ) 27000

= 20000 + 7000

= 2 x 10 POWER4 + 7 x 10 ³

c ) -343

= - 300 - 40 - 3

= -3 x 100 - 4 x 10 - 3 x 1

= - 3 x 10² - 4 x 10 - 3 x 1

d) 62500

60,000+2000+500

= 6X 10 power 4+2x 10³ +5 x 10²
