Which of the following numbers is the smallest?

A
1.6×10 with Exponent of -3

B
1.6×10 with Exponent of -5

C
1.6×10 with Exponent of 2

D
1.6×10 with Exponent of -7

Explanation:

The more negative the exponent is, the smaller the number will be. This is only for numbers in scientific notation (which A through D is presented as such).

A positive exponent means move the decimal point to the right. A negative exponent tells us to move the decimal point to the left.

Choice D is the one that moves furthest to the left of all the answer choices.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
