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!
