Rewrite the exponential expression (10x2)4 (102) O 100008 O 10000.76 O 1046 O 10x8

Answer i dont know im so sorry I tried..

Step-by-step explanation:

The meaning of (f + g)(-1) is you substitute -1 to x of whatever polynomial you obtain after adding the polynomials f(x) and g(x).
                    f(x) + g(x) = -2x + 8 + 3x = x + 8
Substitute -1,
                        (f + g)(-1) = -1 + 8 = 7.
Thus, the answer is 7.
