Answer:
20
Step-by-step explanation:
- 6 . 10^-1 / - 3 . 10^-2
= ( - 6 / - 3 ) . ( 10^-1 / 10^-2 )
- 6 / - 3 = 2
10^-1 / 10^-2
Formula : -
a^b / a^c = a^( b - c )
Here,
a = 10
b = - 1
c = - 2
10^-1 / 10^-2
= 10^( - 1 - ( - 2 ) )
= 10^( - 1 + 2 )
= 10^1
= 10
( - 6 / - 3 ) . ( 10^-1 / 10^-2 )
= 2 . 10
= 20
