What is the value of 2x^4 / x^3 when x = 0?
This is a nice example of a discontinuous function, meaning it does not exist for all possible values of x. When x has any value other than x=0, the expression is equivalent to 2x. A graph would look like a straight line, gradient 2, passing through the origin - but with a hole at the exact point where it should go through the origin.

Is it true that President Obama once wore a "Belgian suit" (costume belge)?
Quite possibly, but more famously he wore a 'costume beige' - a tan suit that was the talk of the media as an inappropriate colour for a serious meeting. The 'tan suit incident' has gotten a fair bit of mileage over the years.

How accurately can a wild elephant throw a rock?
It depends on how you'd attempt to define accuracy, but accurate enough to hit moving cars, or hit the hand of a man in a parked truck, or a rhino at a relatively short distance.

What is the value of 2x^4 / x^3 when x = 0?
I think a more correct answer is that the limit of (2x^4/x^3) approaches 0 as x approaches 0, but the actual expression is undefined since it involves division by zero. That is, the response above divided x^4 by x^3 or 0/0. (SixShutouts66)

What is the value of 2x^4 / x^3 when x = 0?
First you have to simplify your expression. x^4 / x^3 = x, so the expression is equivalent to 2x. The value of 2x when x = 0 is just 0. (2 * 0 = 0)
2x^4 / x^3 = 2(x^4 / x^3) = 2(x)
2(0) = 0 (TriviaFan22)

In some cultures, it is customary for newly married couples to jointly make the first cut in a 'wedding cake'. What is the origin of this tradition?
One source says it dates back to Victorian times [1], another to the 1950s [2]. But in yet another article that actually explores the history of wedding cakes in Western tradition in great detail with sources, the date is set in the 1930s [3]. This is when couples reportedly began making the first wedding cake cut together as ceremonial act, with the actual cutting and distribution of the cake pieces being done behind the scenes. Prior to this, it may have been the job of the bride to cut and distribute the cake to everyone without the groom's assistance.
Incidentally, the quintessential tiered wedding cake is thought to have been popularised by Queen Victoria's massive three-tiered fruitcake weighing over 100kg and measuring about 1m in diameter. As with any tradition and cultural meme, such traditions would have spread through influential pioneers like this.
This is all to say nothing of other cultures outside the Western white wedding tradition, where cake may play an even more central role with different traditions.
