Question

evaluate the expression at specific values of its variables evaluate a^4 - b(c) + 2(a) divided by 2
a = 2 b = 4 and c + 3

Answer 1

I'll assume you mean ((a^4) − b·c + 2a) / 2 and that c = 3.

Substitute a = 2, b = 4, c = 3:
- a^4 = 2^4 = 16
- b·c = 4·3 = 12
- 2a = 2·2 = 4

Numerator: 16 − 12 + 4 = 8
Divide by 2: 8 / 2 = 4

Result: 4

If you meant something different for c or the placement of the division, tell me and I’ll recompute.
