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: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
