Answer: The simplified expression is \(15x^3+30x\)
Step-by-step explanation:
Since we have given that
\(5x(3x^2+6)\)
We need to simplify the expression:
For this we will use "Distributive law":
\(a\times (b+c)=a\times b+a\times c\)
\(5x(3x^2+6)\\\\=5x\times 3x^2+5x\times6\\\\=15x^3+30x\)
Hence, the simplified expression is \(15x^3+30x\)
