If (x ＾ m ＾ x ＾ 2n) ＾ 3 ＾ (x ＾ 2m-1) and 2x are of the same kind, and M + 5N = 13, find m ＾ 2-25n ＾ 2

If (x ＾ m ＾ x ＾ 2n) ＾ 3 ＾ (x ＾ 2m-1) and 2x are of the same kind, and M + 5N = 13, find m ＾ 2-25n ＾ 2

First of all, you must have made a mistake in copying the question. It is estimated that (x ＾ 2m-1) should be (x ＾ 2m-n). Next, solve the problem First of all, it is divided into small steps (x ＾ m ＾ x ＾ 2n) ＾ 3 = (x ＾ 3M ＾ x ＾ 6N) according to the principle of exponential power division with the same base, constant base and exponential subtraction, the original formula = x ^ [3m-6n - (2m-n)] = x ^ (m-5n) ① Simplify

Excuse me: the two items in the following groups are not of the same kind: (a) 2 & # 179;, 3 & # 178; (b) - AB, AB / 2
﹙C﹚5²a ,a² ﹙D﹚4x²y³ ,-y³x²

(a) 2 & # 179;, 3 & # 178; yes
(b) - AB, AB / 2 are
(c) 5-178; a, a-178; No
(d) 4x & # 178; Y & # 179;, - Y & # 179; X & # 178; yes

-P & # 178; - P & # 178; - P & # 178; (merge similar items)
If the third power of 3xy and - 3xy (power 3n) are of the same kind, then M = n =, the merging result is

It is known that a-178; + b-178; - 10a-6b + 34 = 0,
Find the value of (a-b / A + b) &# 178; △ A & # 178; - B & # 178; / AB × A & # 178; + 2Ab + B & # 178; / A & # 178; - B & # 178

a^2+b^2-10a-6b+34=0
a^2-10a+b^2-6b=-34
a^2-10a+25+b^2-6b+9=-34+25+9
(a-5)^2+(b-3)^2=0
∵ and 0
(a-5)^2≥0,(b-3)^2≥0
∴a-5=0,b-3=0
a=5,b=3
The following evaluation, algebra can write some clear? Need to be seen as a whole, please add brackets

Are two items in the following groups similar? Why? ① 2A & # 178; B and 2Ab & # 178; ② 3xy and - 1 / 2yx; ③ - 2.1 and 3 / 4; ④ 2a and 2Ab

Are two items in the following groups similar and why?
① 2a-178; B and 2ab-178;
No, the front a is twice, B is once; and the back a is once, B is twice
② 3xy and - 1 / 2yx
yes
③ - 2.1 and 3 / 4
yes
④ 2A and 2Ab
No, there's no B in the front, there's a B in the back
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

-Are 5 (a-b) ∧ 2 and 3 (B-A) ∧ 2 similar

Yes. (a-b) ^ = (B-A)^

It is judged that 1.5A and 4b are the same category, 2.5ab and - 4AB are the same category, 3.14x & # 178; Y & # 179; and 5Y & # 179; X & # 178; are the same category
4. - 2 and 5 are of the same kind
5.3a+4b=7ab
6.15x²－5x²=10
7.2x+3x=5x²
8.-5m+5m=0

It is wrong to judge that 1.5A and 4b are similar terms
2.5ab and - 4AB are the same category
3.14x & # 178; Y & # 179; is the same as 5Y & # 179; X & # 178; is correct
4. - 2 and 5 are of the same kind
5.3a + 4B = 7ab error cannot merge similar items
6.15x & # 178; - 5x & # 178; = 10 error 10x & # 178;
7.2x + 3x = 5x & # 178; error 5x
8. - 5m + 5m = 0 correct

The congeners of 4AB & # 178; C & # 179; are as follows:
A.4bc²a³ B.4ca²b³ C.¼ac³b² D.¼ac²b³

The term of the same kind refers to the term with the same quantity except the coefficient, so choose C &# 188; AC &# 179; B &# 178;

Write three similar terms of 3x & # 178; Y & # 178; Z arbitrarily

If you don't understand this question, you can ask. If you are satisfied, remember to adopt it
If you have any other questions, please take this question and send it to me. Please understand
I wish you progress in your study!

Please write three similar terms of 2x & # 178; Y & # 179; Z ()

-2x²y³z,1/2x²y³z、7/2x²y³z
As long as the coefficient is changed, it is a similar term, even in itself
