Write log6 5 as a logarithm of base 4.
a)log base 4 of 5 over log base 4 of 6
b) log base 4 of 6 over log base 4 of 5
c)log base 5 of 4 over log base 6 of 4
d)log base 6 of 4 over log base 5 of 4

It is a).

Step-by-step explanation:

The rule for change of base of a log is:

logb x =  = loga x / loga b

So we have

log6 5 = log4 5 / log4 6.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

the answer is (-4,-4)

hope this ! : d
