Changing bases to evaluate logarithms in exercise, use the change-of-base formula and a calculator to evaluate the logarithm. see example 9.
log6 10

1.2850

Step-by-step explanation:

Using the change of base formula,

Log 10 to base 6 = Log 10 ÷ Log 6

Log 10 = 1

Log 6 = 0.7782

Log 10 ÷ Log 6 = 1 ÷ 0.7782 = 1.2850

step-by-step explanation:

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:
