What is the LCM for (x + 3)2(x – 2) and (x + 3)(x2 – 16)? A. (x + 3) B. (x + 3)(x – 2)(x – 16) C. (x + 3)3(x – 2)(x2 + 16) D. (x + 3)2(x – 2)(x2 – 16)

2(x-2)(x+3)(x-8)

Step-by-step explanation:

The LCM of and is x + 3

Option A is correct

The task is to find the LCM of the expressions:

and

Note that:

Therefore, the expression will become:

By considering the expressions and , it is observed that x + 3 is common to both expressions.

Therefore, the LCM of and is x + 3

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:
