Answer 1

`\large\boxed{\tt -18x^(7)}`

Explanation:

`\textsf{We are asked to simplify the given expression.}`

`\tt 2x^3 * -9x^4`

`\large\underline{\textsf{Rule of Multiplying Exponents;}}`

`\textsf{Remember that Exponents represent how many times the term is being multiplied}`

`\textsf{to itself. Whenever we are multiplying 2 terms with exponents, the exponents will}`

`\textsf{\underline{add}. When we are multiplying coefficients, we just multiply like we're multiplying 2}`

`\textsf{whole numbers.}`

`\large\underline{\textsf{Simplifying;}}`

`\textsf{Apply the Multiplication Rule for Exponents.}`

`\tt 2x^3 * -9x^4 \rightarrow (2x * -9x)^(3+4) \rightarrow \large\boxed{\tt -18x^(7)}`
