confused from where I left off PLEASE help

Not sure the right equation so i did both....
#1 - √12m√15m=1m√2
Simplifies to:
13.416408m2=1.414214m
Let's solve your equation step-by-step.
13.416408m2=1.414214m
Step 1: Subtract 1.414214m from both sides.
13.416408m2−1.414214m=1.414214m−1.414214m
13.416408m2−1.414214m=0
Step 2: Factor left side of equation.
m(13.416408m−1.414214)=0
Step 3: Set factors equal to 0.
m=0 or 13.416408m−1.414214=0
m=0 or m=0.105409
Answer: m=0 or m=0.105409
#2 - √12m√15m
Simplifies to:
13.416408m2
=13.416408*m2
=13.416408*(m*m)
=13.416408m2
Can I get a brainliest Please & Thank you...
I believe [1] and [2] are again placeholders, and not the numbers 1 and 2. Combine the square roots on the left side:
[tex]\sqrt{12m}\cdot\sqrt{15m}=\sqrt{12m\cdot15m}=\sqrt{180m^2}[/tex]
Notice that
[tex]180=2^2\cdot3^2\cdot5[/tex]
so we have
[tex]\sqrt{180m^2}=\sqrt{2^2\cdot3^2\cdot5\cdotm^2}=\sqrt{(2\cdot3\cdot m)^2\cdot5}=\sqrt{(2\cdot3\cdotm)^2}\cdot\sqrt5[/tex]
[tex]=\sqrt{(6m)^2}\cdot\sqrt5=6m\sqrt5[/tex]
(where [tex]\sqrt{m^2}=m[/tex] only if [tex]m\ge0[/tex])
So I would imagine the solution is [1] = 6 and [2] = 5.
