Answer:

Step-by-step explanation:
The equation is ,
- Here e is the Euler's Number . The log which are defined on the base e are called Natural logarithms.
Say if we have a expoteintial equation ,
In logarithmic form it is ,

Similarly our required answer will be ,

Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :

The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
1.7a + 0.3a = 0.8;
(1.7 + 0.3)a = 0.8;
2 x a = 0.8;
a = 0.8 ÷2;
a = 0.4;
