PLEASE HELP WITH THIS!

The rate of a hypothetical reaction involving L and M is found to triple when the concentration of L is doubled and to double when the concentration of M is doubled. Write the rate law for this reaction.

I am trying to help my daughter with this exact problem. Could you explain to me how you solve for l and m to get the rate law? It's been a long time since I've been in chemistry class and I homeschool her. Thank you for you help.

3=2L => log3=L log2 => L=log3 / log2

So would the rate law be: rate = k[L]^1.5[M]? It's a half integer which confuses me.

rate=k[L]ˆ1.58 [M] to be precise. Orders often are whole numbers, but they don't have to be.
