Answer:
Q3: A
Q4: 9x² + (-x) + (-3)
Step-by-step explanation:
Q3: C (63) => x = 63. => C(x) = 36 x 63
Q4: f(x) + g(x) = 7x² - 5x + 3 + 2x² + 4x - 6 = (7x² + 2x²) + (-5x + 4x) + (3 - 6) = 9x² + (-x) + (-3)

Answer:
   a.  6
   b.  9
Step-by-step explanation:
a. The product modulo 7 can be found from the product of the individual numbers modulo 7:
   (88·95·36·702) mod 7 = (88 mod 7)·(95 mod 7)·(36 mod 7)·(703 mod 7) mod 7
   = (4·4·1·3) mod 7 = 48 mod 7 = 6
__
b. Powers of 4 mod 11 repeat with period 5:
   4 mod 11 = 4
   4^2 mod 11 = 5
   4^3 mod 11 = 9
   4^4 mod 11 = 3
   4^5 mod 11 = 1
So, 4^83 mod 11 = 4^3 mod 11 = 9
