Q. The decimal expansion of the rational number 12 to the power 4 and 5 to the power 3 will terminate after how many places of decimal ?
=> (i) 12 ^ 4 , when calculated will come a whole number. This means it has no decimal expansion. So , it isn't a decimal number. So , we can say that it will terminate after 0 places of decimal .
=> (ii) 5^3 , when calculated will come a whole number.This means it has no decimal expansion. So , it isn't a decimal number. So , we can say that it will terminate after 0 places of decimal. The condition for 5 ^4 is same as that of 5^3.
