4.25 / 2.5 simple calculation

4.25/2.5
=4.25×4/（2.5×4）
=17/10
=1.7

8 * 2.5 * 1.25 * 4

=（8*1.25）*（2.5*4）
=10*10
=100

Simple calculation: 4.2 / 4 + 3.8 * 25%

4.2/4+3.8*25%
=4.2*25%+3.8*25%
=(4.2+3.8)*25%
=8*25%
=2

1÷32÷0.05÷0.25÷0.5，=1÷（4×8）÷0.05÷0.25÷0.5，=1÷4÷8÷0.05÷0.25÷0.5，=1÷（4×0.25）÷（0.05×8×0.5），=1÷1÷0.2，=5．

2.5 × 0.32 × 1.25

2.5×0.32×1.25
=2.5×0.4x0.8×1.25
=(2.5x0.4)x(1.25x0.8)
=1x1
=1

The absolute value of (a + 3) + 4B ^ 2 + 4B + 1 = 0 to find the value of 6b-2a / A + B

Absolute value of (a + 3) + 4B ^ 2 + 4B + 1 = 0
Absolute value of (a + 3) + (2B + 1) ^ 2 = 0
The absolute value of (a + 3) = 0, (2B + 1) ^ 2 = 0
a=-3
b=-1/2
(6b-2a)/(a+b)
=[6*(-1/2)-2*(-3)]/(-3-1/2)
=(-3+6)/(-7/2)
=3/(-7/2)
=-3*2/7
=-6/7

The value of a is determined by the square of the root 9-6a + A + the root A-4 = a

∵√(9-6a+a²)+√(a-4)=a
∴√(a-3)²+√(a-4)=a
∵a-4≥0,∴a-3＞0
∴a-3+√(a-4)=a
∴√(a-4)=3
a-4=9
a=13

The power of 2007 of [(15 under the root) + 4] multiplied by the power of 2008 of [4 - (15 under the root)] =?

(√15+4)^2007*(4-√15)^2008
=[(4+√15)(4-√15)]^2007*(4-√15)
=1^2007*(4-√15)
=4-√15

Definition: if a + B is equal to 2, then a and B are equal to 1
X-3 and -------- are the equilibrium numbers of 1

According to the definition, when a + B = 2, we call a and B the equilibrium number of 1,
Let X and X - 3 be equilibrium numbers about 1
x - 3 + X = 2
So x = 2 - (x - 3) = 5 - X
Therefore, X - 3 and 5 - X are equilibrium numbers about 1
