Question

3. Express each of the following numbers using exponential notation:
(a) 12,500
(b) 27,000
(C) -343
​

Answer 1

Answer:

Step-by-step explanation:

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
