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

2854

Explanation:

Answer 2

The given expression is
81x²y³ + z

When x=3, y=4, z=19, then
81x²y³ + z
= 81*(3²)*(4³) + 19
= 81*9*64 + 19
= 46,675

Answer: D 46,675
