Rewriting a number in its expanded form with exponents helps you to better understand scientific notation. When determining what exponent to use for a power of ten, look at how many zeroes you have. For example, if the number is 1,000, which has three zeroes, it is 10 to the third power.
7025 = 7*103 [+ 0*102] + 2*101 + 5*100 The bit in the square brackets can be skipped if you are expert enough and your exam board allows it.
7,025 = (7 x 103) + (0 x 102) + (2 x 101) + (5 x 100)
