The expressions that simplifies to 41 are:
a) 10 + 2³ * 4 - 1
d) 10 + (2³ * 4) - 1
Information about the problem:
a) 10 + 2³ * 4 - 1
b) 10 + 2³ * (4 - 1)
c) (10 + 2³) * 4 - 1
d) 10 + (2³ * 4) - 1
We solve the equations respecting the level of hierarchy:
- First the operations in parentheses, then brackets and finally braces.
- Of the arithmetic operations, first the multiplication and divisions and then the additions and subtractions.
a) 10 + 2³ * 4 - 1
10 + 8*4 - 1
10 + 32 - 1
42 - 1
41 (it applies)
b) 10 + 2³ * (4 - 1)
10 + 8 * (3)
10 + 24
34 (it doesn't applies)
c) (10 + 2³) * 4 - 1
(10 + 8) * 4 - 1
18*4 - 1
72 - 1
71 (it doesn't applies)
d) 10 + (2³ * 4) - 1
10 + (8*4) - 1
10 + 32 -1
42 - 1
41 (it applies)
<h3>What are algebraic operations?</h3>We can say that they are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, division among others.

Answer:
------------------------------------------------------
- Since, 12² = 144 and 13² = 169, the square root of 150 is between 12 and 13.
- Then, you can pick any two whole numbers less than 13 and multiple them by 1/8.
- Remember that multiplying by 1/8 is the same that dividing by 8.
- Choose 12 and 11, for instance, and two rational numbers that are less than 1/8 of the actual side length are 12/8 and 11/8.
- 12/8 can be simplified to 3/2 and 11/8 is in its simplest form.
- Thus, two rational numbers that are within 1/8 of the actual side length of the bulletin board are 3/2 and 11/8.
