The sum of three continuous even numbers is 36. Let the number in the middle be x and the equation be

（x-2)+x+(x+2)=36

Logarithmic operation (㏒ 10 √ 27 + ㏒ 10 8-3 ㏒ 10 √ 10) / ㏒ 10 1.2

log√27=0.5log27=0.5*3log3=1.5log3
log8=3log2
-3log√10=-3*0.5=-1.5
Denominator = log1.2 = log12 - log10 = log4 + log3 - 1 = 2log2 + log3 - 1
Molecule = 1.5log3 + 3log2-1.5 = 1.5 (log3 + 2log2-1)
=>The original formula is 1.5.ans

(1+0.12+0.23)X(0.12+0.23+0.34)-(1+0.12+0.23+0.34)X(0.12+0.23)
If a {B = 3a-2b, find 2} (& # 160; 3} 4 & # 160; & # 160; & # 160; & # 160; & # 160;)

1. The original formula = 1 * (0.12 + 0.23 + 0.34) + (0.12 + 0.23 + 0.34) * (0.12 + 0.23) - [1 * (0.12 + 0.23) + (0.12 + 0.23) * (0.12 + 0.23 + 0.34)] = (0.12 + 0.23 + 0.34) + (0.12 + 0.23 + 0.34) * (0.12 + 0.23) - (0.12 + 0.23) * (0.12 + 0.23 + 0.34) =

It is known that a = - 3x-2mx + 3x + 1, B = 2x + MX-1, and the value of 2A + 3b is independent of X, so we can find the value of M

2A + 3B = 5mx + 6x-1 = (5m + 6) X-1 if this value has nothing to do with X, we can only let 5m + 6 = 0
So m = 6 / 5 is 1.2

Let f (x) = ax ^ 3 + 3 / 2 (2a-1) x ^ 2-6x. If f (x) is an increasing function in the interval from negative infinity to - 3, find the value range of real number a
To be specific, 3Q

If the derivative f (x) '= 3ax ^ 2 + 3 / (2a-1) x-6f (x) is an increasing function in the interval (- infinity, - 3), then f (x)' = 3ax ^ 2 + 3 / (2a-1) X-6 > 0. According to the image (parabola) characteristics of quadratic function, the small root of equation 3ax ^ 2 + 3 / (2a-1) X-6 = 0 can only be ≥ - 3

How many square meters is 400 square meters for 5 hectares

1 hectare = 10000 square meters, so it's 50400 square meters

Given the function f (x) = x * 3-x, then the tangent equation of the curve y = f (x) at the point m (2, f (2))

f'(x)=3x^2-1
f(2)=6
The slope f '(2) = 11 and a point m (2,6)
The tangent equation is y = 11x-16
I'm a sophomore in high school. I have no experience. I'm not to blame for my mistakes

How much is 1995 multiplied by 1996 minus 1 / 1995 + 1994 multiplied by 1996

1995 times 1996 minus one point 1995 + 1994 times 1996
=(1994 + 1) times 1996 minus one point 1995 + 1994 times 1996
=1994 times 1996 + 1995 / 1995 + 1994 times 1996
=1

What is 12 less than 75% of 60? (equation)

Let this number be X
x+12=60*75%
x+12=45
x=33
The number is 33
