Answer 2

Answer:

Step-by-step explanation:

According to Remainder Theorem, if a polynomial f(x) is divided by ( x - a), then f(a) will be the remainder.

f(x) = 8x⁴ + 8x^7 + 7 and a = -1/2

f(-1/2) = 8(-1/2)⁴ + 8(-1/2)^7 + 7

= 8 x (1/16) - 8 x (1/128) + 7

= 1/2 - 1/16 + 7 = (8 - 1 + 112)/16 = 119/16
