Please help me with these!!

1. I believe p=43. For (x^7)^3, you multiply the both exponents, and get (x^21). When it looks like (x^22)(x^21), you add the exponents and get (x^43).

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
