The simplified form of the expression 3w × 3x⁹ × 5w⁷ × x⁹ is 45w⁸x¹⁸.

What is the simplified form of the expression?

Given the expression in the question:

3w × 3x⁹ × 5w⁷ × x⁹

To simplify the expression 3w × 3x⁹ × 5w⁷ × x⁹, we use the rules of exponentiation and multiplication.

3w × 3x⁹ × 5w⁷ × x⁹

Simplify the coefficients of the variable 'w' together.

3w × 5w⁷ × 3x⁹ × x⁹

Multiply 3 and 5 to get 15:

15w × w⁷ × 3x⁹ × x⁹

Simplify the 'w' terms by adding their exponents:

15w¹⁺⁷ × 3x⁹ × x⁹

Simplify the 'x' terms by adding their exponents:

15w¹⁺⁷ × 3x⁹⁺⁹

15w⁸ × 3x¹⁸

Furthermore, simplify it by multiplying 15 and 3:

45w⁸x¹⁸

Therefore, the simplified form is 45w⁸x¹⁸.
