Expland the following logarithm: 5log_4(a) - 6log_4(b)​

Hi there! We are given the expression:

To condense or simplify the following logarithm. You have to remember these properties:

Properties - Logarithm

These two properties are what we need for our problem. Therefore,

We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.

Answer

Any questions can be asked through comment as I may reply soon. Thanks for using ! Have a good day and happy learning! :)

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:
