Factor x^4–y^4 completely. The expression x 4 − y 4 is a difference of squares, which can be factored as follows: x 4 − y 4 = (x 2) 2 − (y 2) 2. This can be factored into: (x 2 + y 2) (x 2 − y 2) The term x 2 − y 2 is also a difference of squares, which can be factored further: x …

= (x2)2 −(y2)2. Apply Difference of Two Squares Formula: x2 −y2 =(x+y)(x−y) (x2)2 −(y2)2 = (x2 +y2)(x2 −y2) = (x2 +y2)(x2 −y2) = (x2 +y2)(x+y)(x−y) What is factor x^4-y^4 ?

The answer is = −x3(5 −x4)−43 Explanation: Let's do the differentiation x4 +y4 = 5 4x3+4y3 dxdy = 0 ... \left. \begin {cases} { 8x+2y = 46 } \\ { 7x+3y = 47 } \end {cases} \right. Solve your math problems using our free math solver with step-by-step solutions.

Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.

Solve an equation, inequality or a system.

y4 y 4 を (y2)2 (y 2) 2 に書き換えます。 (x2)2 −(y2)2 (x 2) 2 - (y 2) 2. 両項とも完全平方なので、平方の差の公式 a2 − b2 = (a+b)(a−b) a 2 - b 2 = (a + b) (a - b) を利用して、因数分解します。 このとき、 a = x2 a = x 2 であり、 b = y2 b = y 2 です。 (x2 + y2)(x2 − y2) (x 2 + y 2) (x 2 - y 2) 因数分解。 タップして手順をさらに表示してください… (x2 + y2)(x+y)(x−y) (x 2 + y 2) (x + y) …

2020年5月1日 · You can see by expanding that 3 3 terms are perfect squares, so you can attempt (x2 + a. xy +y2)2 (x 2 + a. x y + y 2) 2 and see what's left, with a coefficient for xy x y since this is unsure how much xy x y there is.

《比例对数表》和《比例四线新表》分别给出了1～10000的六位对数表和六位三角函数对数表。 书中把今天所说的“对数”称为“比例数”或“假数”，并简单解释了把乘除运算化为加减运算的道理。 这是对数方法在中国的首次介绍。 对数是17世纪最重要的发现之一，它有效地简化了繁重的计算工作。 在对数、解析几何和微积分这三种当时西方最重要的数学方法中，也只有对数比较及时地 …
