Hey mates,☺️
=============
Plz solve this..
=============
Thnx :)

Answer 1

1.057×10^-4

=(1057/1000) ×10^-4

=(1057/10^2)×10^-4

=1057/(10^2×10^4)

=1057/10^6 [a^m×a^n=a^m+n]

=0.001057 ans.

6.987×10^6

=(6897/1000)×10^6

=(6897/10^3)×10^6

=6897×10^-3×10^6

=6897×10^3

=6897000 ans

Answer 2

Answer:

1)1057*10^-8

0.00001057

2)6897*10^3

6987000

Step-by-step explanation:

since

a^n/a^m=a^(m-n)

where m and n is real number
