Simplify: (- 3x ^ 3)(- 2x ^ 5)
A.- 5x ^ 15
B.6x ^ 15
C.- 5x ^ 8
D. 6x ^ 8
To simplify the expression (-3x^3)(-2x^5), we can multiply the coefficients (-3)(-2), getting 6. According to the power of x, we combine the exponents by adding them: 3 + 5 = 8. Therefore, the simplified expression is 6x^8.
The correct answer is D. 6x^8.
To simplify (-3x^3)(-2x^5), we can multiply the coefficients (numbers) and add the exponents of the variables.
The coefficient -3 multiplied by -2 is 6.
The exponent of x is the sum of the exponents on the variables x. In this case, we add 3 and 5, which gives 8.
Therefore, the simplified expression is 6x^8.
So, the answer is D. 6x^8.
