For part (ii) use the same logic as it is given in the part (i).thanks but part ii is still unclear why 6 to power 3 is this a new rule
The first digit is fixed i.e. 5.
For the second digit, you have 6 numbers to choose from. For the third again you have 6 digits to choose from and so on.
So the no. of possibilities will become : 6*6*6 = 6^3
