Dividing throughout by 64 ("8" for and ) gave the triple (24, 5/2, 1), which when composed with itself gave the desired integer solution (1151, 120, 1). Brahmagupta solved many Pell's equations with this method, proving that it gives solutions starting from an integer solution of x 2 − N y 2 = k {\displaystyle x^{2}-Ny^{2}=k} for k = ±1, ±2 ...
Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
Adam Ondra on the sport climbing route Silence, the hardest free climbing route in the world and the first-ever at 9c (French), 5.15d (American YDS), and XII+ (UIAA).. The two main free climbing grading systems (which include the two main free climbing disciplines of sport climbing and traditional climbing) are the "French numerical system" and the "American YDS system".

Unlike many other phenethylamines, 2C drugs, including 2C-C, 2C-D, 2C-E, 2C-I, and 2C-T-2 among others, are inactive as monoamine releasing agents and reuptake inhibitors. [ 6 ] [ 11 ] [ 8 ] [ 7 ] [ 10 ] Most of the 2C drugs are agonists of the rat and mouse trace amine-associated receptor 1 (TAAR1).
The rows with minterm m(4,12) and m(10,11,14,15) can now be removed, together with all the columns they cover. The second prime implicant can be 'covered' by the third and fourth, and the third prime implicant can be 'covered' by the second and first, and neither is thus essential.
For example, for 2 5 a + 1 there are 3 increases as 1 iterates to 2, 1, 2, 1, and finally to 2 so the result is 3 3 a + 2; for 2 2 a + 1 there is only 1 increase as 1 rises to 2 and falls to 1 so the result is 3a + 1. When b is 2 k − 1 then there will be k rises and the result will be 3 k a + 3 k − 1.
For instance, to solve the inequality 4x < 2x + 1 ≤ 3x + 2, it is not possible to isolate x in any one part of the inequality through addition or subtraction. Instead, the inequalities must be solved independently, yielding x < 1 / 2 and x ≥ −1 respectively, which can be combined into the final solution −1 ≤ x < 1 / 2 .
