Hello, so here we have an equation, 3x squared all to the minus 1 is equal to 3x to the minus 2.
00:08
So is this true? well, so what is 3x to the minus 1? well, this means we can take basically anything to a negative exponent means 1 over whatever this is to the same power.
00:19
So negative 1 just takes the reciprocal.
00:22
So 3x squared to the minus 1, that's 1 over 3x squared.
00:28
And we're saying, is that equal to 3x to the minus 2? well, x to the minus 2 means 1 over x to the 2.
00:35
But that exponent, because this whole thing is not in parentheses, only affects the x.
00:41
So therefore, this is saying this is equal to, well, 3 times 1 over x squared.
00:48
So that would be, well, 3 over x squared.
00:52
So is 1 over 3x squared equal to 3 over x squared? well, no.
00:56
So therefore, this equation is false...
