Introduction

In algebra, simplifying expressions is a crucial skill that helps us solve complex equations and problems. It involves combining like terms, removing unnecessary factors, and rearranging the expression to make it more manageable. In this article, we will focus on simplifying the given expression, which involves multiplying and combining like terms.

The Given Expression

The given expression is:

${ -8x^6y \times 2x^4y^5 \times \left(-7x^{10}y \cdot 6^2\right) }$

This expression involves multiplying three terms together, each of which contains variables and constants. Our goal is to simplify this expression by combining like terms and removing unnecessary factors.

Step 1: Multiply the Constants

To simplify the expression, we start by multiplying the constants together. The constants in the given expression are -8, 2, and -7. We multiply these numbers together to get:

${ -8 \times 2 \times -7 = 112 }$

So, the constant term in the simplified expression is 112.

Step 2: Multiply the Variables

Next, we multiply the variables together. The variables in the given expression are x^6, x^4, x^10, y, and y^5. We multiply these variables together to get:

${ x^6 \times x^4 \times x^{10} \times y \times y^5 = x^{20}y^6 }$

So, the variable term in the simplified expression is x^20y6.

Step 3: Combine the Terms

Now that we have multiplied the constants and variables together, we can combine the terms to get the simplified expression. We multiply the constant term (112) by the variable term (x^20y6) to get:

${ 112x^{20}y^6 }$

This is the simplified expression.

Simplified Expression

The simplified expression is:

${ 112x^{20}y^6 }$

This expression is much simpler than the original expression, and it is easier to work with.

Conclusion

Simplifying expressions is an important skill in algebra, and it involves combining like terms, removing unnecessary factors, and rearranging the expression to make it more manageable. In this article, we simplified the given expression by multiplying the constants and variables together and combining the terms. The simplified expression is 112x^20y6.
