Evaluate the expression 263 + 5 when b = 3.<br> 263 +5 = 2(3): +5<br> =
ExtremeBDS [4]

Given:

The expression is:

2b^3+5

To find:

The value of the given expression when b=3.

Solution:

We have,

2b^3+5

Substituting b=3 in the above expression, we get

2b^3+5=2(3)^3+5

2b^3+5=2(27)+5

2b^3+5=54+5

2b^3+5=59

Therefore, the value of given expression at b=3 is 59.

First, let's see how 23 compares with the squares of the positive whole numbers on the number line.

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

The value of 23 is right between the square of 4 and the square of 5. Thus, the value √23 will be between 4 and 5.

Since 23 is much, much closer to the square of 5 than the square of 4, we can assume that the value √23 will be closer to 5 on the number line than 4.

Look at the attached image to see where I plotted the approximate location of √23.

You will realize that this approximation is pretty close since the actual value is roughly 4.80.

Let me know if you need any clarifications, thanks!
