Evaluate: log1255
a.1/3
b.1/2
c. 2/3

Step-by-step explanation:

Using the rule of logarithms

x = n ⇔ x =

let 5 = n, then

5 =

note that 125 = 5³ ⇒ =

Since bases are equal ( both 5) equate the exponents

3n = 1 ( divide both sides by 3 )

n =

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
