Answer:36x^13
Explanation:
We can solve this problem using the rule of exponents: (am)n = amn.
First, let's simplify the exponent on the first term:
(-3x^5)^2 = (-3x^5) × (-3x^5)
Next, let's multiply this by 4x^3:
(-3x^5)^2 × 4x^3 = (-3x^5) × (-3x^5) × 4x^3
Now, let's multiply the coefficients and combine the exponents:
(-3 × -3)x^(5 + 5 + 3) = 36x^13
Therefore, the answer is 36x^13.
