Answer 1

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
