its 8

Step-by-step explanation:

as you divide the left number by 2 you multiply the right by 2 each time, see the pattern

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

you just switch the numbers basically so it would be 3/17
