Answer 2

Answer:

-64

Step-by-step explanation:

Lets expand this:

x*x*x*x*x*x*x*xx*x*x*x*x*x...(for 72 times) + x^w = x*x*x*x*x*x*x*x

now lets put this x^72 to the another side...by doing so we get:

x^w = x^8*x^72

So it is 8-72 = -64

We can think this as - when we add something and get something low. it is understood that it is negative

for example:

4+(-2) = 2

So, it is understood that we need to minus it!!

Hope this helps
