Solved 4 Does A B 2 Always Equal A2 2ab B2 Does Chegg Answer to 4. does (a b)2 always equal a2 2ab b2 ? does. upload image. special symbols. This isn't true in general since $a$ and $b$ might not commute. the most that we can say is $$ (a b)^2=(a b)(a b)=a^2 ab ba b^2 $$.
Solved 2ab 4b 2 For A 5 And B 2 Chegg Specifically, (a b) 2 generally cannot equal (a 2 b 2), because with (a b) 2, the same thing is being multiplied everywhere (namely, (a b)), while with (a 2 b 2), a and b are being multiplied by different things (namely, a and b respectively). Since matrix multiplication does not commute, you'll actually get. a^2 ab ba b^2. no, the formula (a b) = a 2ab b is a property of numbers called the binomial expansion, and it does not apply to matrices. in general, matrix operations such as addition and multiplication have different rules and properties than those of numbers. Suppose that a and b are unspecified 2 x 2 matrices. is the quantity given always equal to (a b)2? (a) a2 2ab b2 yes o no (b) (b a)2 yes no (c) a (a b) b (a b) yes no (d) a2 ab ba b2 yes no. your solution’s ready to go! our expert help has broken down your problem into an easy to learn solution you can count on. Here’s the best way to solve it. for problem 5, to determine which matrices are guaranteed to equal (a b) 2, start by expanding (a b) 2 using the distributive property of matrix multiplication. 5. which of the following matrices are guaranteed to equal (a b)2? a2 2ab b2, a (a b)b (a b), (ab) (b a), a2 ab ba b2 6.

A and b will yield the same value as each other irrespective of the values of variables substituted for the variables. in other words, a = b is an identity if a and b define the same functions. they may appear to be defined in different ways but are equal. for example: (a b) 2 = a 2 2ab b 2 (a b) 3 = a 3 3a 2 b 3ab 2 b 3. 见解析证明如下：(a b)2=(a b)×(a b)=a×(a b) b×(a b)=a2 a×b b×a b2=a2 2ab b2公式(a b)2=a2 2ab b2称作两数和的平方公式，也叫完全平方公式，这是初等数学中常用的公式．使用公式时应注意：(a b)2≠a2 b2(这里a和b都不为零)．两数和的平方公式还. Assume that all matrices are n n. (a b)^2 = a2 2ab b2 a. (a b)^2 = a2 ab − ab b2 = a2 b2. this is only equal to a2 2ab b2 when a = 0nn or b = 0nn, which in general is not true. b.
