Answer:
The first number is
72.6
Step-by-step explanation:
Let second number be x.
First number= 6x
Third number= 3x
According to question,
6x+x+3x=121
or, 10x=121
or,x=121/10=12.1
First number= 6x=6×12.1=72.6
Third number=3x=3×12.1=36.3
It is good equation. Look, that:
81 = 3 x 3 x 3 x 3 = 3^4.
So you have to solve:
3^x = 3^4
exponents have to be the same, so
x=4
That's mean that A(4) = 81
