two hundred and sixty
Are you a child? If you want to find the least common multiple, you can list the multiples of two numbers. Look at the least common multiple. There is also a short division method, which is available in the book. Take a good look

What is the least common multiple of 52 and 30?

780

What is the least common multiple of 15 and 13?

195, of course

If (4x + y) & # 178; + 3 (4x + y) - 4 = 0, then the value of 4x + y is ()
① If (4x + y) &# 178; + 3 (4x + y) - 4 = 0, then 4x + y is ()
Variant 1: (A & # 178; + B & # 178;) &# 178; - (A & # 178; + B & # 178;) - 6 = 0, then a & # 178; + B & # 178; = ()
If variant 2: (x + y) (2-x-y) + 3 = 0, then the value of X + y is ()
Variant 3: X & # 178; + XY + y = 14, Y & # 178; + XY + x = 28, then the value of X + y is ()

Let T ^ 2 + B ^ 2 be TT ^ 2-t-6 = 0, t = 2 or T = - 32

If 2n-6 and 3N + 1 are the square roots of the same number, find the number

Two cases
（1）
2n-6=3n+1
n=-7
3n+=1=-20
This number is 400
（2）
2n-6=-(3n+1)
n=1
2n-6=-4
The number is 16

If the two square roots of the positive number a are 3N + 1 and 4n-15, find the real number a

The two square roots of a are opposite to each other
So (3N + 1) + (4n-15) = 0
7n-14=0
7n=14
n=2
So one of the square roots of a is 3 × 2 + 1 = 7, so a is 7 & # 178; = 49

An irrational number is a number whose square root is endless, right

It's not right
Infinite non cyclic decimal is called irrational number
π is also irrational (omitted) It's also irrational

If the maximum value in the inequality 2x-1 ≤ 13 is m and the minimum value in the inequality-3x-1 ≤ - 7 is n, then what is the solution set of the inequality NX + Mn < MX

m=7 n=2

The inequality mx-2n > NX + Mn + 2 with respect to X

mx-2n>nx+mn+2
mx-nx>2n+mn+2
M-N = 0 0 > 2n + Mn + 2 2n + Mn + 20 x has no solution
m-n>0 x>(2n+mn+2)/ (m-n) ；m-n

4 / 5 times 1 / 8 times 16

Four out of five times one out of eight times 16
=1\8*16*4\5
=2*4\5
=8\5
eight-fifths
