10 to the 9th power is: 1,000,000,000
103 = 10 x 10 x 10
109 or, if you prefer, 1.0*109
4.2 × 103 written in standard form is 4,200
10 to the 17th power.
10 to the 9th power is: 1,000,000,000
103 = 1,000
103 = 10 x 10 x 10
103 = 10 x 10 x 10
0.006 times 10 to the 3rd power is: 0.006 x 103 = 6
3.4 x 103 = 3,400
109 or, if you prefer, 1.0*109
6.7 x 10^9 = 6,700,000,000
10 to the power of 3. 103
2.8 x 109 = 2,800,000,000
4.2 × 103 written in standard form is 4,200
100 = 1 101 = 10 102 = 100 (10 x 10) 103 = 1000 (10 x 10 x 10) - which is the answer to this question.
