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.
In Scientific notation, the number 70.0765 will be 7.65 x 10 to the
power of -2. To reach this answer, you first need to move the decimal
point to the right, until the number becomes significant. In this
instance, you only need to move the decimal two places. Every movement
of the decimal means that you multiplying 10, so as this has been done
twice in this case your final answer needs to be to power of -2.
