Log8 2 = x
by the definition of logs, we can write
8^x = 2
8^(1/3) = 2
so x = 1/3
or we could solve it by using log to base 10 and use our calculator
log 8^x = log 2
x log 8 = log 2
x = log 2 / log 8 = 0.333.... = 1/3
You just need to try with all of the pair f.ex
0,-2 -> put 0 in the x-> y=8*0-2=-2 so ok it is q possible pair of the function..
You try every pair till you find set where all the pairs fit
So set 1
1 and 6: 8*1-2=6 ok
2 and 14 : 8*2-2=14 ok
Hope I could help
The answer is x equals 62
