Question

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

these are the numbers to the letters a = 2 b = 4 and c = 3

Answer 1

Interpret the expression as (a^4 − b·c + 2a) / 2.

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
Result = 8 / 2 = 4

So the value is 4.

(If you instead meant only 2a to be divided by 2—i.e. a^4 − b·c + (2a)/2—the value would be 6.)
