Question

The expression 0.00222 x 10^n is greater than 2 (and n is an integer). what is the smallest possible value for n

Answer 1

The smallest value for n is -3
When you move the decimal point to the right, the exponent on the 10 will be negative
move the decimal point to the right 3 times and you get 2.22 x 10^-3
2.22 is greater than two
