Solve each equation by square roots. 1. 4^2=81

2. (4−3)^2+7=39

3. 2^2−2=6

4. 13^2−3=4209

5. 10(−7)^2=440

ou would have 12 of each

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:

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

47
