Combine and simplify these radicals. square root of 3 times the square root of 16

Step-by-step explanation:

square root of 3 times the square root of 16 looks like this

we try to break the numbers inside the radical to there prime factors

so

the prime factors which are in pair , comes out of the radical so

which simplifies to

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:
