1. (2-3)`1 i.e raise to power 1

2.X3 /X`5 i.e X raise to power 3 divided by X raised to power -5.

I think the answer to question 2, is X^8.
Because in indices, when dividing its -.
Then -×- equal +.
I might be wrong oh.

For question 1, anything raised to power 1 equals to that thing/number. So do your bracket arithmetic first.

can u explain well on this?

I'm not a good teacher, let me try
In indices there are laws, That's the laws of indices.
One of them states that, when dividing you subtract and when multiplying you add.


So since it's dividing we are doing here,
We subtract but remember, the denominator has a - sign. So in maths - - equals +.
