Answer:
Now factor of 10 is = 5 × 2
Now to break the base number into 5 or 2
So, for 25 = 25
33 = 33
48 = (2 × 2)8 = 216
53 = 53
67 = (2 × 3)7 = 27 × 37
76 = 76
812 = (2 × 2 × 2)12 = 236
99 = 96
106 = (2 × 5)6 = 26 × 56
1512 = (5 × 3)12 = 512 × 312
2014 = (5 × 2 × 2)14 = 514 × 228
2211 = (11 × 2)11 = 1111 × 211
2515 = (5 × 5)15 = 530
So total = 2109 × 565
We can ignore rest of the factors
⇒ 1065 × 244
So, power of 10 is 65
⇒ n = 65
