Easy
remember
(x^m)(x^n)=x^(m+n)
basically add exponens when the base is same
(13^-11)(13^16)(13^-3)(13^4)(13^-5)=
13^(-11+16-3+4-5)=
13^(5-4)=
13^1=13

Step-by-step explanation:
20-9 is 11
Answer:
The answer to this problem is 4
Step-by-step explanation:
To work out the LCM, we need their prime factors. So:
2 is simple 2 x 1.
7 is also 7 x 1.
13 is also 13 and 1.
They all have in common "1" - so we keep that aside as 1 figure, rather than 3.
We still have the 2, 7 and 13 leftover.
We then multiply the 1 with the other figures.
So 1 x 2 x 7 x 13 is our answer.
Which is = 182.
