This is not an equation.
I can tell, there's no equal sign.

(2r+3t)^4.  Find the product.
Ok, we can do that.
You can square it, then squared it again.
I would use Pascal's triangle.
The 4th power --> 1 4 6 4 1
-----
{{{(2r+3t)^4 = (2r)^4 + 4(2r)^3(3t) + 6(2r)^2(3t)^2 + 4(2r)(3t)^3 + (3t)^4}}}
Multiply the terms, you're done.
