From the question we were told that 2^13 is approximately equal to 8000. We are asked to find the best approximation for 2^26.

In this question, we will have to use the formulas of power addition given by:

If we have:

x^a * x^b = x^a+b

(x^a)^b = x^ab

So now let's consider the scenario we are given.

recall, the best appriximation o 2^13 is 8000.

Then the best approximation for 2^26.

Now we have: 26 = 13 * 2

So, we can we can have:

2^13 ------ 8000

squaring both side:

(2^13)^2 --------- (8000)^2

= (2)^13*2 --------- 64000000

= 2^26 -------- 64000000

Therefore,

2^26 = 64,000,000 (best approximation).
