Answer:
Step-by-step explanation:
the subtraction symbol means that you will be finding the difference
6x^4-10x^4
the exponents will stay as they are because they are the same
you just have to combine the like terms 6x^4 and 10x^4
a term is separated by a symbol (in this case it is a subtraction symbol)
6x-10x=-4x
so you will just put the exponent back in place and your answer will be
-4x^4
