In order to write in scientific notation you have to write an expression with a whole number times 10 to a certain exponent. In this case the nearest whole number would be 7.65 and you have to move the decimal place twice to the left to get the desired number. Thus, the exponent would be a negative number. The final answer is : 7.65 x 10^-2.
To write a number in scientific notation, you need to write the number as the product of a number from 1 to under 10 and an integer power of 10.
Start by moving the decimal point until you have a number from 1 to under 10.
By moving the decimal point 2 places to the right, you end up with 7.65 which is from 1 to under 10. Having moved the decimal point 2 places to the right, you multiplied the number by 100. Now you need to divide 7.65 by 100 to get back to the original number.
