"Could anyone help with this formula

[16^(26-25-1)]

I can work the second part out but powers have never been my strong subject.

What is the second part?

I am sure you know 26 -25 -1 = 0

So, 16^(26 -25 -1) = 16^0

Then, any number raised to zero is equal to 1

so, 16^(26 -25 -1) = 16^0 = 1 -----answer.

--------------

Or do you mean this way?:

16^(26 -25 -1)

= 16^(26 -26)

= 16^26 *16^(-26)

= 16^26 *1 / 16^26

= 16^26 / 16^26

= 1
