To solve this multiplication, you need to multiply the coefficients (-7 and 3) and the variables (x and x^3).
Multiply -7 and 3 to get -21. Then, multiply x and x^3 to get x^(1+3) = x^4.
Therefore, -7x * 3x^3 is equal to -21x^4.

8x^2 * (-2y^2) = ?
To solve this multiplication, you need to multiply the coefficients (8 and -2) and the variables (x^2 and y^2).
Multiply 8 and -2 to get -16. Then, multiply x^2 and y^2 to get (x^2) * (y^2) = x^(2+0) * y^(0+2) = x^2 * y^2.
Therefore, 8x^2 * (-2y^2) is equal to -16x^2 * y^2.
Multiply 8 and -2 to get -16. Then, multiply x^2 and y^2 to get (x^2) * (y^2) = x^(2+0) * y^(0+2) = x^2 * y^2.
Therefore, 8x^2 * (-2y^2) is equal to -16x^2 * y^2.
-5x^3y (-3y^2) =?
To solve this multiplication, you need to multiply the coefficients (-5 and -3), the variables (x^3y and y^2).
Multiply -5 and -3 to get 15. Then, multiply x^3y and y^2 to get x^(3+0) * y^(1+2) = x^3 * y^3.
Therefore, -5x^3y * (-3y^2) is equal to 15x^3y^3.
Multiply -5 and -3 to get 15. Then, multiply x^3y and y^2 to get x^(3+0) * y^(1+2) = x^3 * y^3.
Therefore, -5x^3y * (-3y^2) is equal to 15x^3y^3.
-10m^2 * (2mn^3) * (-mn) = ?
To solve this multiplication, you need to multiply the coefficients (-10, 2, -1), the variables (m^2, mn^3, mn).
Multiply -10, 2, and -1 to get 20. Then, multiply m^2, mn^3, and mn to get m^(2+1+1) * n^(0+3+1+1) = m^4 * n^5.
Therefore, -10m^2 * (2mn^3) * (-mn) is equal to 20m^4n^5.
Multiply -10, 2, and -1 to get 20. Then, multiply m^2, mn^3, and mn to get m^(2+1+1) * n^(0+3+1+1) = m^4 * n^5.
Therefore, -10m^2 * (2mn^3) * (-mn) is equal to 20m^4n^5.
