Answer 3

Solving the Equations

To solve the given equations, we need to place the appropriate arithmetic operations and, if necessary, parentheses to make the equations true. Let's solve each equation step by step:

1. 38 _ 29 _ 6 = 54

To make this equation true, we need to determine the missing arithmetic operations and parentheses. Let's start by evaluating the expression inside the parentheses first:

38 _ (29 _ 6) = 38 _ 174 = 6,012

So, the equation becomes:

38 _ 29 _ 6 = 6,012

2. 53 _ 5 _ 8 = 6

To make this equation true, we need to determine the missing arithmetic operations and parentheses. Let's start by evaluating the expression inside the parentheses first:

(53 _ 5) _ 8 = 265 _ 8 = 2,120

So, the equation becomes:

53 _ 5 _ 8 = 2,120

3. 48 _ 8 _ 8 = 7

To make this equation true, we need to determine the missing arithmetic operations and parentheses. Let's start by evaluating the expression inside the parentheses first:

(48 _ 8) _ 8 = 384 _ 8 = 3,072

So, the equation becomes:

48 _ 8 _ 8 = 3,072

4. 87 _ 60 _ 3 = 30

To make this equation true, we need to determine the missing arithmetic operations and parentheses. Let's start by evaluating the expression inside the parentheses first:

(87 _ 60) _ 3 = 5,220 _ 3 = 15,660

So, the equation becomes:

87 _ 60 _ 3 = 15,660

Summary

After solving each equation step by step, we have the following results:

1. 38 _ 29 _ 6 = 6,012 2. 53 _ 5 _ 8 = 2,120 3. 48 _ 8 _ 8 = 3,072 4. 87 _ 60 _ 3 = 15,660

These are the solutions to the given equations.
