Which of the following is the product of the rational expression shown below?

A

Step-by-step explanation: Do 2x multiplied by (x+2) to get 2x^2 as denominator. Then do 3 times 7, which is 21 for the numerator.

42

step-by-step explanation:

256/6=42

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
