Answer:
The simplified expression is [tex]30w^{11}x^9[/tex]
Therefore the simplified expression to the given expression is [tex]3w^4.5x^8w^7.2x=30w^{11}x^9[/tex]
Step-by-step explanation:
Given expression is [tex]3w^4.5x^8w^7.2x[/tex]
To simplify the given expression as below :
[tex]3w^4.5x^8w^7.2x[/tex]
First combine the like terms to simplify the expression easily we get
[tex]=(3.5.2)(w^4.w^7)(x^8.x)[/tex]
[tex]=30(w^{4+7})(x^{8+1})[/tex] ( by using the property [tex]a^m.a^n=a^{m+n}[/tex] )
[tex]=30w^{11}x^9[/tex]
Therefore the simplified expression is [tex]30w^{11}x^9[/tex]
Therefore the simplified expression to the given expression is [tex]3w^4.5x^8w^7.2x=30w^{11}x^9[/tex]
