Understanding the Problem

To simplify the given expression, we need to apply the rules of exponents and multiplication. The expression is $\left(-2 x^3\right)^2 \cdot y \cdot y^9$ . We will start by simplifying the exponent of the binomial $-2 x^3$ .

Simplifying the Exponent of the Binomial

When we have a binomial raised to a power, we need to apply the power to each term inside the binomial. In this case, we have $\left(-2 x^3\right)^2$ . Using the power rule of exponents, we can rewrite this as $(-2)^2 \cdot (x^3)^2$ .

Applying the Power Rule of Exponents

The power rule of exponents states that for any numbers $a$ and $b$ and any integer $n$ , $(ab)^n = a^n \cdot b^n$ . We can apply this rule to simplify the expression $(-2)^2 \cdot (x^3)^2$ . This gives us $4 \cdot x^{3 \cdot 2}$ .

Simplifying the Expression

Using the rule of exponents that states $x^m \cdot x^n = x^{m+n}$ , we can simplify the expression $4 \cdot x^{3 \cdot 2}$ to $4 \cdot x^6$ .

Multiplying the Terms

Now that we have simplified the exponent of the binomial, we can multiply the terms together. We have $4 \cdot x^6 \cdot y \cdot y^9$ . Using the rule of exponents that states $x^m \cdot x^n = x^{m+n}$ , we can simplify this expression to $4 \cdot x^6 \cdot y^{1+9}$ .

Simplifying the Exponent of y

Using the rule of exponents that states $x^m \cdot x^n = x^{m+n}$ , we can simplify the expression $y^{1+9}$ to $y^{10}$ .

Combining the Terms

Now that we have simplified the exponent of y, we can combine the terms together. We have $4 \cdot x^6 \cdot y^{10}$ . This is the simplified form of the original expression.

Conclusion

In conclusion, the simplified form of the expression $\left(-2 x^3\right)^2 \cdot y \cdot y^9$ is $4 \cdot x^6 \cdot y^{10}$ , which can be written as $4 x^6 y^{10}$ .
