Answer:
4 * 10^9
2.7 * 10^-8
6.776 * 10^7
9.05*10^4
5.409*10^5
9.04 * 10^-3
3.2 * 10^-2
5.12 * 10^8
Explanation:
1. 4,000,000,000
4 * 1,000,000,000 = 4 * (10*10*10*10*10*10*10*10*10) = 4 * 10^9
2. 0.000000027
27 * 10^-9 = 2.7 * 10^-8
0.000000027 = 2.7 * 10^-8
3. 67,760,000 = 6776 * 10000
6776 * 10000 = 6776 * 10^4
6776 * 10^4 = 6.776 * 10^3 * 10^4 = 6.776 * 10^7
4. 90,500
905 * 100 = (9.05 * 100) * 100
(9.05*100) * 100 = 9.05 * 10^2 * 10^2 = 9.05*10^4
5. 540,900
5409 * 100 = (5.409 * 1000) * 100
(5.409*1000)*100 = 5.409*10^3 * 10^2
5.409*10^3 * 10^2 = 5.409*10^5
6.) 0.00904
0.00904 = 904 * 10^-5
904 * 10^-5 = 9.04 * 10^-3
7. 0.032
32 * 10^-3 = 3.2 * 10^-2
8. 512,000,000
512 * 1000000
512 * 10^6 = 5.12 * 10^2 * 10^6 = 5.12 * 10^8
