15 tsp of black pepper was used. 2 half tsp = one whole tsp. 12 half tsp is equivalent to 6 tsp. Multiply 1 1/4 by 12 and you get 15. <span />
24q^2 / 8q^-3
lets break this down...
24/8 = 3
q^2 / q^-3....when dividing exponents with the same base, keep the base and subtract the exponents. q^2 / q^-3 = q^(2 -(-3) = q^(2 + 3) = q^5
put them together and u get : 3q^5
or can be written as 
<h3>Further explanation</h3>
This is a question about the composition of functions and how to get a domain function.
Given
and
.
We will form (b o a)(x) and then determine the domain.
<u>Step-1</u>

Replace each appearance of x in b(x) with
.

Thus, 
<u>Step-2</u>
To be defined, the value under the radical sign must not be negative. Therefore, the domain of
are processed as follows.

Both sides added by 3.

Both sides divided by 3.

Thus, the domain of
is
or can be written as

which means there is some integer

for which

.
Because

and

, there are integers

such that

and

, and

We have

, which means there are four possible choices of

:
1, 42
2, 21
3, 14
6, 7
which is to say there are also four corresponding choices for

:
9, 378
18, 189
27, 126
54, 63
whose sums are:
387
207
153
117
So the least possible value of

is 117.
