Okay to do scientific notation, move your decimal behind the first number 9.256 not there is 12 decimal places we moved to get to 9.256 and we moved to the left so we would do an exponent of -12 and we all ways to scientific notation with _ ×10_ so the way 0.000000000009256 will be made in to scientific notation is
