Q. 474.3( 6 Votes )
A rational number in its decimal expansion is 327.7081. what can you say about the prime factors of q when this is number is expressed in the form P/q? give reasons
Answer :
The decimal number 327.7081 can be written in the form of a fraction 
⇒ 
Here, q = 10000
The prime factors of 10000 are 2 and 5.
∵ 10000 = 10⁴
= (2 × 5)⁴
= 24 × 54 (law of exponent (ab)m = am b m)
