We are now going to have a look at the Fridrich method. This is the fastest and the easiest Rubik’s cube solving method. Most of the world fastest speedcubing athletes use the Fridrich method to solve the Rubik’s cube. It is the key to solve the cube under 20 seconds or even 10 seconds if you really master the method.

CFOP method
Solution: He used the CFOP method to solve the cube.Nov 25, 2018
Guinness World Records has certified the largest Rubik’s Cube in the world at the NINA MALL in Hong Kong. At 2.503 meters x 2.505 meters x 2.502 meters, it officially became the largest Rubik’s Cube on March 28.
Solving a Rubik’s cube is often thought to be one of the hardest challenges to overcome in life. Once mastered, though, you won’t just receive a boost of self-confidence, but if you continue toward the more difficult and challenging puzzles, you’ll start to notice your cognitive abilities increase.
5.8%
Less than 5.8% of the world’s population can solve the Rubik’s Cube, according to the Rubik’s website.Jun 23, 2018
The current Unofficial World Record for the 1×1 is 8 minutes 59 seconds.
CFOP method
For the standard 3x3x3 Rubik’s Cube, I use the CFOP method. CFOP stands for Cross, F2L, OLL, and PLL, which are the four main stages of this solving method. Essentially, this method solves the cube in layers—the cross and F2L stages solve the first two layers of the cube, and I do this intuitively.Jan 18, 2019

∴ 243 is not a perfect cube. … i.e. 216 is a perfect cube. ∴ The smallest number required to multiply 72 to make it a perfect cube is 3.
Answer: 8, 27, 64 are the cube numbers 100.
There is an analogous formula for the general quartic equation, ax4 + bx3 + cx2 + dx + e = 0 . … The formulas for the roots of a general quartic are listed and derived there. The derivation requires the solution of the general cubic (for which we give only hints at the derivation).
are said to be depressed. They are much simpler than general cubics, but are fundamental, because the study of any cubic may be reduced by a simple change of variable to that of a depressed cubic.
Any cubic formula built solely out of field operations, continuous functions, and radicals must contain nested radicals. … There does not exist any quintic formula built out of a finite combination of field operations, continuous functions, and radicals.
