Help me in this problem.

2(4) + 3(4)³ ≠ 5(4)⁴

Step-by-step explanation:

To determine if the two expressions, 2y + 3y³ is the same as 5y⁴, we can set both expressions equal to each other. Then replace y with a value to find out, if what you have on the both sides are equal or not.

Thus: 2y + 3y³ = 5y⁴

Replace y with 4 in the equation

2(4) + 3(4)³ = 5(4)⁴

8 + 192 = 1,280

200 ≠ 1,280

What we have on one side of the equation is not equal to what we have in the other side. So therefore, both expressions are not equal. Hence, they are not the same.

The statement that shows 2y + 3y³ and 5y⁴ are not the same is:

2(4) + 3(4)³ ≠ 5(4)⁴
