Which is NOT equivalent to (x^4 )^3 ? A) x^12
B) (x^4)(x^8)
C) (x^3)^4
D) (x^6)(x^2)

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:

the answer is:

mean: 6

mad: 2.14
