F (a + b) = f (a) * f (b)

F (a + b) = f (a) * f (b)

F (x) = m ^ x (where m is a nonzero real number, for example, 2,3,...) )
f(a+b)=m^(a+b)=(m^a)(m^b)=f(a)f(b)

The standard form of the linear equation with one variable of X is ax + B = 0. Why change the equation x + (2x-1) = 3 to the standard form

x+(2x-1)=3
3x-1=3
3x-4=0

More than one people, singular or plural?
More than two people

More than one person + singular predicate
More than two people + plural predicate

It is known that from △ ABC, ∠ B = 60 °, ab = 6, AC = 3 √ 6, then the area of triangle is,

Through a as ad ⊥ BC in D,
Then BD = 1 / 2Ab = 3, ad = 3 √ 3,
∴DC=√(AC^2-AD^2)=3√3
In this way, there is only one case (DC > BD, no two cases)
BC=3+3√3.
SΔABC=1/2*BC*AD=1/2(3+3√3)*3√3=9√3/2+27/2
