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
