The conclusion is that both gym charge the same, because the identity 75 = 75 means that the two equations are equivalent (the same).

Answer:</h2>
The value is:
-4
<h2>
Step-by-step explanation:</h2>
We are asked to find the value of the ceiling function: 
As we know that the ceiling function always occupy the higher value in integers.
i.e. the ceiling function act as follows:
it takes value 0 when -1< x≤0
1 when 0 < x ≤ 1
2 when 1 < x ≤2
and so on.
As we know that:
-4.6 lie between -5 and -4.
Hence, we have:

(-2a^5b^4) * (42ab^6) = -84a^6b^10
