Question

If log3 base 2 +log2 base x=10/3=logy base2+log2 base y and x not equals to y then x+y=?​

Answer 1

Step-by-step explanation:

You can go faster by dividing by powers of two (instead of dividing 5 times by 2, divide by 32 and add 5 to your counter, etc.) You can have a more precise answer by comparing with others value whom you know the log. For instance, 1.875 is bigger than sqrt(2), so log2(15) is in [3.5,4] and not in [3, 3.5].
