Question

What is the value of begin expression . . . 81 times x raised to the second power, times y raised to the third power, plus z . . . end exression, if x equals 3, y equals 4, and z equals 19? A 2,854 B 5,851 C 46,656 D 46,675

Answer 1

((81x² • y³) + z)

1. (81 • 3)² = 59,049
2. (4)³ = 64
3. ((59,049 • 64) + 19) = 3,779,155

... are you sure those were the only answers to be chosen from? and that you typed them in correctly? because if so they don't seem to make any sense unless, I input something incorrectly.
