Final answer:
In scientific notation, really big numbers (greater than one) are expressed as a coefficient multiplied by 10 raised to a certain power.
Step-by-step explanation:
In scientific notation, really big numbers (greater than one) are expressed as a coefficient multiplied by 10 raised to a certain power. The exponent on the ten indicates the number of factors of 10 in the original number. For example, if we have the number 1,000,000, we can write it in scientific notation as 1 x 10^6. Here, the exponent on the ten is 6, which means there are 6 factors of 10 in the original number.
