Question

Please help me with this problem so I can better help my son understand. I have attached an image of what were working on. Multiply.−3/10xy(60xy^6)

Answer 1

`-(3)/(10)xy(60xy^6)=`

Combining similar terms:

`\begin{gathered} =(-(3)/(10)\cdot60)(x\cdot x)(y\cdot y^6)= \\ =-18(x\cdot x)(y\cdot y^6)= \end{gathered}`

Applying the product rule of exponents:

`\begin{gathered} =-18(x^(1+1))(y^(1+6))= \\ =-18x^2y^7 \end{gathered}`
