What is 16,700,000,000,000,000 estimated as the product of a single digit and a power of 10
Vesna [10]
Hello!

Another way to put it would be scientific notation. to do so, you would need to get a digit 1-10 multiplied by 10 to a certain power.

For this problem, scientific notation is 1.67(10^16).

To check our answer,  we will move the decimal to the right sixteen times because the exponent is positive. In other words, we will add fourteen zeros because we need two to turn 1.67 into 167. This gives us 16,700,000,000,000,000, which matches the question. (This number in word form is 16 quadrillion seven hundred trillion.)

Our final answer is 1.67(10^16).

I hope this helps!
