Answer:
The first common multiple is 60
Step-by-step explanation:
The first common multiple can be found by making a list of multiples of each number and finding the first one that is the same:
12x1=12
12x2=24
12x3=36
12x4=48
12x5=60
15x1=15
15x2=30
15x3=45
15x4=60
Notice that 12x5=60 and 15x4=60
This is the first multiple they have in common, therefore 60 is the first common multiple.

Answer:
7^22
Step-by-step explanation
Given the expression
7^8 × 7^3 × 7^4 × 7^7
In indices
a^m × a^n = a^{m+n}
The powers are added since the base are the same
We ate going to add all the powers of the expression given since they have the same base which is 7
7^8 × 7^3 × 7^4 × 7^7
= 7^{8+3+4+7}
= 7^22
= 3.91×10^18
We can use the inverse function derivative theorem:
In this case, we want to evaluate , so:
The derivative is:
The ordinate of the point is , so we evaluate:
Finally:
We can check the answer by finding the inverse:
so that
Therefore:
Which finally gives the same answer as before:
