Calculating A to the Power 4
To calculate A to the power of 4, you simply multiply A by itself 4 times. So, A to the power of 4 can be written as A x A x A x A.

Expanding 4A Square
4A square means 4 times A squared. A squared is A x A, so 4A squared is 4 x A x A, which simplifies to 4A^2.

Subtracting 5
Subtracting 5 from the expression 4A^2 gives us 4A^2 - 5.

Putting it all together
So, if we have the expression A to the power of 4 - (4A^2 - 5), we can simplify it by substituting A to the power of 4 as A x A x A x A, and 4A^2 as 4 x A x A.
Therefore, the expression simplifies to A x A x A x A - (4 x A x A) - 5, which further simplifies to A^4 - 4A^2 - 5.
This is the final expression after expanding and simplifying the given expression.
