if k is an integer and 0.0010101 x 10 ^ k is greater than 100 , what is the least possible value of k ?
"0.0010101 * 10 ^ k > 100 we need to move the decimal point to the right 5 places to get 101.01 this is equivalent to multiplying by 10 ^ 5 . the answer is d ."
divide(log(divide(100, 0.0010101)), log(10))
