if k is an integer and 0.00010101 x 10 ^ k is greater than 10 , what is the least possible value of k ?
"0.00010101 * 10 ^ k > 10 we need to move the decimal point to the right 5 places to get 10.101 this is equivalent to multiplying by 10 ^ 5 . the answer is c ."
divide(log(divide(10, 0.00010101)), log(10))
