#979000.#

The exponent on the 10 is going to tell you how many spaces to move the decimal point.

But your next question might be, "Well, how do I know which way to move the decimal point, left or right?"

When going from scientific notation to standard notation, like your problem, think of a number line enter image source here

If the exponent is positive, it is on the right side of the number line because it is a positive number#=>#

So, you would move the value of the exponent right if it were positive

But, if the exponent were negative, the number is on the left side of the number line because it is negative.

So you would move the decimal point the exponents number left

But since your problem is positive, we will be moving the decimal to the right

#9.79xx10^5#

The exponent says to move #5# spaces to the right

#979000.#

Fill in the empty spaces with zero after you move the decimal point
