Question

Express the exponential number 2.25 x 10-4 as an ordinary number. 22,500 0.000 022 5 225,000 0.000 225 none of the above

Answer 1

For this case we have the following number:
2.25 x 10-4
We observe that it is written in exponential notation.
The exponent is negative, therefore, we must move the point to the left.
We have then:
2.25 x 10-4 = 0.000225
Answer:
0.000225
