Answer:
log(13/4)
Step-by-step explanation:
The property of logarithms of interest here is ...
log(a) + log(b) = log(ab)
Using a=13/5 and b=5/4, we find ...
log(13/5) + log(5/4) = log((13/5)(5/4)) = log(13/4)

Answer:
Truth value of ~(~p) is same as the truth value of p.
Step-by-step explanation:
For any statement p the truth table for p, ~p and ~(~p) will be as the figure attached. In this table we know that If truth value for p is true then ~p will be false and ~(~p) will be true which is same truth value as truth value of p.
Now if the truth value of any statement is false then truth value for ~p will be true and for ~(~p) will be false which is again similar to the statement p.
Hence truth value of any statement p is similar to the truth value of ~(~p).
Answer:
sq root of 64 = 8, sq root of 81 = 9, 8 and 9
