Final answer:
To evaluate the expression nᵏ - 2b + 8 when b = 1.5, k = 8, and n = 7, substitute the given values into the expression and simplify the arithmetic.
Step-by-step explanation:
To evaluate the expression nᵏ - 2b + 8 when b = 1.5, k = 8, and n = 7, substitute the given values into the expression.
So, the expression becomes: 7⁸ - 2(1.5) + 8.
To simplify this, first calculate 7⁸, which equals 5764801. Then, multiply 2(1.5) to get 3. Finally, add the values: 5764801 - 3 + 8 = 5764806.
Therefore, the expression evaluates to 5764806.
