(-2)^2 = 2^2l og3 81 = x
then 3x = 81
3x = 34
therefore x = 4
11= 1
10 = 1
11 = 10
1 = 0
Why is this wrong / right ????
While your arithmetic is correct he is not simplifying the RHS and LHS he is claiming that for any number b1^0 = 1
so 1 = 1
oh lol right he's doing it with the powers wtfWhile your arithmetic is correct he is not simplifying the RHS and LHS he is claiming that for any number b
B^m = B^N implies m=n clearly not true sorry stuck in train
I'm not comparing the bases ie (-2 and 2).(-2)^2 = 2^2
Does this mean -2 = 2 ?
Yep that makes sense. ThanksExactly what I have said thy
1^1 = 1^2 = 1^3 = 1^n = ..... For n integral excluding infinity we cannot say 1=2=3=...=n
But its the same general concept: If f(a) = f(b), that doesn't mean a=bI'm not comparing the bases ie (-2 and 2).
I'm looking at the exponents ie x and 4 then 1 and 0
