Answer 2

Solution :

**************************************
By Exponential Laws :

i ) a^0 = 1

ii ) 1/a^-n = aⁿ

********************************†*****

Now ,

( 4^0 + 5^-1 ) × 5² × 1/3

= ( 1 + 1/5 ) × 5²/3

=[ ( 5 + 1 )/5 ] × ( 5 × 5 )/3

= 6/5 × ( 5 × 5 )/3

After cancellation , we get

= 2 × 5

= 10
