Question 1188215: Find y
Y= log base 6 of 1

And
Y=log base 64 of 8
I don't understand how to do these . If you can provide explation that would be really helpful even for just one of them.
Thanks in advance.

.

(a)  Y = log%286%2C%281%29%29 = 0.


     It is BECAUSE  6%5E0 = 1.


     For ANY BASE b > 0  and any real number x > 0,  log%28b%2C%28x%29%29 = 0,    BECAUSE  x%5E0 = 1.




(b)  To calculate  log%2864%2C8%29,  notice that  64^(1/2) = 8 = sqrt%2864%29.


     THREFORE,  log%2864%2C8%29 = 1%2F2.


     EXPLANATION :  log%28b%2Cx%29  is the DEGREE to raise the number b  (the base), to get the number x.
