How to calculate 1.5x + 20 = 1x (50-x)?
1.5X+20=1×（50-X）
1.5x+20=50-x
1.5x+x=50-20
2.5x=30
x=30÷2.5
x=12
How to calculate 1.5x-1 = x + 1?
1.5X-X=1+1
0.5X=2
X=4
The definite integral (0,1) process of 2 / (x + 1)
Original function = 2ln (x + 1), definite integral = 2ln2

Divide natural numbers from 1 to 30 into two groups, so that the product a of all numbers in the first group can be divided by the product B of all numbers in the second group, then the minimum value of a / B is
A 1077205 B1077207 C 1077209 D 1077211
The natural numbers from 1 to 30 are divided into two groups, so that the product a of all numbers in the first group can be divided by the product B of all numbers in the second group,
The minimum value of a / B is (a) 1077205
Calculation: 3 times root sign 1000-1 / 5 root sign 2 and 1 / 4 + 1 / 2 root sign 0.01-3 times root sign - 3 and 3 / 8
Radical 3 + π - 2 / 3 (accurate to 0.01)
The root number of 3 times is 1000-1 / 5 root number 2 and 1 / 4 + 1 / 2 root number 0.01-3 root number - 3 and 3 / 8
=10-1/5*3/2+1/2*0.1-3*（-3/2）
=10-0.3+0.05+4.5
=14.25
Radical 3 + π - 2 / 3 (accurate to 0.01)
≈1.732+3.142-0.667
≈4.21
