Question

How do I solve

13x²y³·3xy⁵=

Answer 1

Step 1. Gather like terms


`13*3 x^(2) xy^(3) y^(5)`

Step 2. Use product rule:
`x^(a) x^(b) = x^(a+b)`


`13*3 x^(2+1) y^(3+5)`

Step 3. Simplify
`2+1` to
`3`


`13*3 x^(3) y^(3+5)`

Step 4. Simplify
`3+5` to
`8`


`13*3 x^(3) y^(8)`

Step 5. Simplify


`39 x^(3) y^(8)`

Done!
