Simplify the expression:

\[ 3w \cdot 3x^9 \cdot 5w^7x^9 \]

Answer :

To simplify the given mathematical expression, 3w*3x⁹*5w⁷x⁹, we can apply the properties of exponents and multiplication. So, the simplified form of the given expression is 45w⁸ x¹⁸.

To simplify the given mathematical expression, 3w*3x⁹*5w⁷x⁹, we can apply the properties of exponents and multiplication.
First, let's combine the coefficients:

3 x 3 x 5 = 9 x 5 = 45
Next, we'll combine like terms, which in this case are the variables w and x, using the property of exponents that states:

[tex]a^m[/tex] . [tex]a^n[/tex] = [tex]a^{m+n[/tex]
For the w-terms:

w . w⁷ = w ⁽¹⁺⁷⁾ = w⁸
For the x-terms:

x⁹ . x⁹ = x⁹⁺⁹ = x¹⁸
Combining the coefficient with the simplified variables gives us the final simplified expression:
45w⁸ x¹⁸
So, the simplified form of the given expression is 45w⁸ x¹⁸.
