Log3 a/3 = ??????????????????????????

Naddik [55]

We have that
Log3 a/3
Rewrite log3(a/3) using the change of base formula

we know that
The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0.
so
loga(x)=logb(x)/logb(a)
Substitute in values for the variables in the change of base formula

in this problem
b=10
a=3
x=a/3

log3(a/3)=[log (a/3)]/[log (3)]

the answer is
[log (a/3)]/[log (3)]

MArishka [77]

Answer:

Step-by-step explanation:

U= {A,B,C,D,E,F,G}

X = {A, B, C, D}

Y = {A, C, E, F}

a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}

B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}

c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}
