What is log subscript 5 baseline (4 times 7) + log subscript 5 baseline 2 written as a single log?
log subscript 5 baseline 21
log subscript 5 baseline 26
log subscript 5 baseline 30
log subscript 5 baseline 56

(log Subscript 5 Baseline 56)

Step-by-step explanation:

On this question, we have to remember basically of one property: the sum of the same base logarithms.

The sum of the same base Logarithms is equal to the product of it. We'll use in this question twice, to decompose the log of (4*7) and then to solve the sum of it all.

By the way,

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
