4)(a^4)^2 : (а^3)^2=а^2

Answer 2

It looks like you've provided a list of mathematical expressions, but some of them are incomplete or unclear. I'll do my best to interpret and explain each of them:

1. (a) * a This expression represents the multiplication of the variable 'a' by itself. It can be simplified to 'a^2' or 'a squared.'

2. (-a) * a : a This expression first multiplies '-a' by 'a' and then divides the result by 'a.' The 'a' in the denominator cancels out with one of the 'a's in the numerator, leaving you with '-a' as the final result.

3. (-a) : () This expression is incomplete because it lacks a denominator. In mathematical notation, a division operation (a fraction) requires a numerator and a denominator. Without a denominator, it's not possible to evaluate this expression.

4. (a) : (а) This expression appears to represent division, with 'a' in the numerator and 'а' (assuming it's a different variable, not just a different font for 'a') in the denominator. The result of this expression would be 'a/а,' which is equivalent to '1' as long as 'а' is not equal to zero. If 'а' is zero, the expression would be undefined since division by zero is not allowed in mathematics.
