Explain how you would write 0.0553 in scientific notation?

Answer 1

0.0553

In order to write a number in scientific notation, we must leave only one whole number before the decimal point.

Since in our case we need to move the decimal point two places to the right, we have to write the new decimal number 5.53 and multiply it by 10-2 (understand that power of 10 is -2 because we moved the decimal point two places to the right, or we divided the given number by 100, or we multiplied the given number by 1/100 which is the same as 10-2).

Thus,

0.0553 = 5.53 x 10-2
