This seemingly complex expression can be tamed with a systematic approach, and we'll guide you through each step to arrive at the correct answer.

Delving into the Expression: A Step-by-Step Solution

To solve this mathematical puzzle, we'll meticulously follow the order of operations, a fundamental principle in mathematics that dictates the sequence in which operations should be performed. This ensures we arrive at the accurate result.

1. Substitution: Replacing 'm' with its Value

The first step in our journey is to replace the variable m with its given value, which is 6. This substitution transforms the expression into a purely numerical one, paving the way for further simplification. So, we substitute m = 6 into the expression:

46m23=46(6)23-4 \sqrt[3]{-6m^2} = -4 \sqrt[3]{-6(6)^2}

2. Exponentiation: Squaring the Value of 6

Next, we encounter an exponent, the superscript 2 attached to the number 6. This signifies that we need to square the value of 6, which means multiplying it by itself:

6² = 6 * 6 = 36

Now, our expression transforms further:

46(6)23=46363-4 \sqrt[3]{-6(6)^2} = -4 \sqrt[3]{-6 * 36}

3. Multiplication: Multiplying -6 by 36

Moving along, we encounter a multiplication operation within the cube root. We need to multiply -6 by 36:

-6 * 36 = -216

Our expression now takes the form:

46363=42163-4 \sqrt[3]{-6 * 36} = -4 \sqrt[3]{-216}

4. Cube Root: Finding the Cube Root of -216

The heart of our expression lies within the cube root, symbolized by the radical sign with a small 3 as its index. This operation asks us to find a number that, when multiplied by itself three times, equals -216. In this case, the cube root of -216 is -6:

2163=6\sqrt[3]{-216} = -6

Our expression simplifies further:

42163=4(6)-4 \sqrt[3]{-216} = -4 * (-6)

5. Final Multiplication: Multiplying -4 by -6

Finally, we arrive at the last operation, a simple multiplication. We need to multiply -4 by -6. Remember, when multiplying two negative numbers, the result is positive:

-4 * (-6) = 24

Thus, the final value of the expression is:

46m23=24-4 \sqrt[3]{-6m^2} = 24

Unveiling the Solution: A Step-by-Step Guide

To accurately evaluate the expression 46m23-4 \sqrt[3]{-6m^2} when m=6m = 6, we must adhere to the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). This ensures that we perform the operations in the correct sequence, leading us to the accurate result.

Step 1: Substitution

The initial step involves replacing the variable m with its given value, which is 6. This substitution transforms the expression from an algebraic form to a numerical one, making it easier to evaluate.

Substituting m=6m = 6 into the expression, we get:

46m23=46(6)23-4 \sqrt[3]{-6m^2} = -4 \sqrt[3]{-6(6)^2}

Step 2: Exponentiation

Next, we encounter an exponent, the superscript 2, which indicates that we need to square the value of 6. Squaring a number means multiplying it by itself.

Calculating 626^2, we have:

62=66=366^2 = 6 * 6 = 36

Our expression now becomes:

46(6)23=46363-4 \sqrt[3]{-6(6)^2} = -4 \sqrt[3]{-6 * 36}

Step 3: Multiplication

Within the cube root, we have a multiplication operation. We need to multiply -6 by 36.

Performing the multiplication:

636=216-6 * 36 = -216

The expression now simplifies to:

46363=42163-4 \sqrt[3]{-6 * 36} = -4 \sqrt[3]{-216}

Step 4: Cube Root

The cube root operation, denoted by the radical symbol with an index of 3, asks us to find a number that, when multiplied by itself three times, equals the radicand (the number under the radical). In this case, we need to find the cube root of -216.

The cube root of -216 is -6, because:

(6)(6)(6)=216(-6) * (-6) * (-6) = -216

Therefore,

2163=6\sqrt[3]{-216} = -6

Our expression now becomes:

42163=4(6)-4 \sqrt[3]{-216} = -4 * (-6)

Step 5: Final Multiplication

The final step involves multiplying -4 by -6. Remember that the product of two negative numbers is positive.

Performing the multiplication:

4(6)=24-4 * (-6) = 24

Therefore, the value of the expression is:

46m23=24-4 \sqrt[3]{-6m^2} = 24
