What is the rest of the question?
Answer:

Step-by-step explanation:
The question to be solved is the following :
Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, and that γ is unique if
. Recall that given two vectors a,b a⊥ b if and only if
where
is the dot product defined in
. Suposse that
. We want to find γ such that
. Given that the dot product can be distributed and that it is linear, the following equation is obtained

Recall that
are both real numbers, so by solving the value of γ, we get that

By construction, this γ is unique if
, since if there was a
such that
, then

Step-by-step explanation: These two decimals are equal to each other because the zeroes in 7.400 don't change it's value.
So, after a decimal point, zeroes don't change the value of the decimal.
So we can simply drop the zeroes to see that 7.4 = 7.4.
