Answer:
here is the your answer
Step-by-step explanation:
Solutions:-
1) Given number = 9.00876×10^-4
=> 9.00876×1/10^4
=> 9.00876×1/10000
Since a^-n = 1/a^n
=> 9.00876/10000
=> 0.000900876
9.00876×10^-4 = 0.000900876
2) Given number = 6.80968×10^7
=> 6.80968×10000000
=> 68096800
6.80968×10^7 = 68096800
3) Given number = 2.0007×10^0
=> 2.0007×1
Since a^0 = 1
=> 2.0007
2.0007×10^0 = 2.0007
4) Given number = 3.1 ×10^9
=> 3.1×1000000000
=> 3100000000
3.1 ×10^9 = 3100000000
5) Given number = 3.079×10^-3
=> 3.079×1/10^3
Since a^-n = 1/a^n
=> 3.079×1/1000
=> 3.079/1000
=> 0.003079
3.079×10^-3 = 0.003079
6)Given number = 7.896856×10^-7
=> 7.896856×1/10^7
Since a^-n = 1/a^n
=> 7.896856×1/10000000
=> 7.896856/10000000
=> 0.0000007896856
7.896856×10^-7 = 0.0000007896856
7) Given number = 2.001× 10^5
=> 2.001×100000
=> 200100
2.001× 10^5 = 200100
8) Given number = 5.55×10^-5
=> 5.55×1/10^5
Since a^-n = 1/a^n
=> 5.55×1/100000
=> 5.55/100000
=> 0.0000555
5.55×10^-5 = 0.0000555
Used formulae:-
- a^-n = 1/a^n
