To evaluate the expression a^ - bc + 4a when a = 2, b = 3, and c = 8, we substitute the given values into the expression and perform the necessary calculations.
Substituting the values, we have:
(2)^ - (3)(8) + 4(2)
First, let's solve the exponent:
(2)^ - (3)(8) + 4(2) = 2^-24 + 8
Next, calculate the exponent:
2^(-24) is equal to 1 / (2^24) = 1 / 16777216
Now, substitute this value back in:
1 / 16777216 + 8
Finally, add the fractions:
1 / 16777216 + 8 = (1 + 8 * 16777216) / 16777216
The final simplified form depends on the level of precision required. If we round to a certain decimal place, the result will vary.
