How do I get a tilted equal sign for an equation?

For example, this is what I am looking for:
Usually for limits where the value is 0 or 1 of a particular expression (e^x) in this case, you might see something like a tilted 45 degrees equal sign, and the value of that expression.
Not sure how to do it here.
Maybe something like a overbrace without the actual overbrace visible?

@marmot I find it wrong: it is not an equality and will confuse the students, rather than help them.

@marmot: Sure, there are conditions imposed onAandB- they both need to have their own respective limits, but that is besides the point here. Do you find the product of the limits is the limit of the products confusing? I find the=1coloured, slanted superscript confusing.

Please ignore whether the math is correct or not correct. This is simply what I have seen around in class, where if we are evaluating the limit at x=0, then clearly e^0 = 1, this is why I have the = 1

If you only want to draw one of those, this might be a bit of an overkill, but if you plan to do several annotations of that kind and wish to have access to more fancy features, this might be a reasonable way to go.
documentclass{article}
usepackage{amsmath}
usepackage{tikz}
usetikzlibrary{tikzmark}
begin{document}
[lim_{xto0}tikzmarknode{ex}{mathrm{e}^x}left(2+4xright)~=~2]
begin{tikzpicture}[overlay,remember picture]
path[red] ([xshift=1pt,yshift=1pt]ex.north east) -- ++(45:{width("=")*1pt-1pt})
node[midway,sloped]{$=$} node[above right=-2pt]{$1$};
end{tikzpicture}
end{document}
Arguably somewhat clearer alternatives include
documentclass{article}
usepackage{mathtools}
usepackage{tikz}
usetikzlibrary{tikzmark}
begin{document}
[lim_{xto0}tikzmarknode{ex}{mathrm{e}^x}left(2+4xright)~=~2]
begin{tikzpicture}[overlay,remember picture]
draw[red,->] ([xshift=1pt,yshift=1pt]ex.north east) --
++(45:{width("$scriptstyle xto0$")*1pt})
node[midway,sloped,above]{$scriptstyle xto0$} node[above right=-1pt]{$1$};
end{tikzpicture}
end{document}
which illustrates what I mean by "more fancy options".
