Answer:

2b³ + 5 = 59

Explanation:

Given information,

→ 2b³ + 5

→ b = 3

Let's solve the expression,

→ 2b³ + 5

→ 2(3)³ + 5

→ 2(27) + 5

→ 54 + 5 = 59

Hence, the answer is 59.

To find the exact answer based on the last step, "
2(3)^3+5", you must use PEMDAS (attached image below)


2(3)^3+5=2*27+5=54+5=59

Thus the answer is 59.

Hope that helps!
