The question is... is X^y * X^z= X^yz always, sometimes, or never a true equation,
The answer is sometimes. In some cases it it and some cases it isn't. An example where it would be true would be X^2 *X^2. Because 2*2=4 and 2+2=4. But an example where it wouldn't would be X^3*X^4=X^7. 4*3 doesn't equal 7.
