Question

Evaluate the expression 2b^3+5 (BTW I did the first part it's 3 but I need the second part)​

Answer 1

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.

Answer 2

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!
