We are asked to express 952 in scientific notation
The scientific notation is given by
The number 952 has the decimal point at the end, so we move this decimal point to the left until there is only one digit is left (9 in this case) and then count the number of times we moved.
In this case, we moved 2 times so the exponent (power) is 2
The sign of exponent is positive when we move to the left (like in this case)
The sign of exponent is negative when we move to the right.
