Answer:

Step-by-step explanation:
The given number is 
We need to write this number in standard form.
Any no is given in the standard form is given by :

Where
a and b is real no and integer
It means,

Hence, this is the required solution.
Andrew can reach a maximum of
high up the wall.
The right-angled triangle formed can be solved using the
ratio. that is

where
is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for
, we get

Since Andrew can reach an extra
above the point where the ladder rests against the wall, the maximum height Andrew can paint is
