Final answer:
The value of 2w²+8x÷3y−4z is 0.
Step-by-step explanation:
To find the value of 2w²+8x÷3y−4z with the given values of w=2, x=6, y=4, and z=3, we substitute these values into the expression:
2w²+8x÷3y−4z = 2(2)²+8(6)÷3(4)−4(3)
Simplifying, we get:
2(4)+48÷12−12
8+4−12
= 0
Therefore, the value of 2w²+8x÷3y−4z when w=2, x=6, y=4, and z=3 is 0.
