The line above the 6 and 3 means that those are recurring, so the full number is 2.63636363.... Recurring numbers can never be defined by decimals, because there is no end to the numbers repeating. It can only be defined by a fraction, so that means the number is irrational. Because it is between integers (a fraction that can't be simplified and will give a recurring decimal), it can't be a real number. All rational numbers are real numbers, but no irrational number can be a real number.
Therefore, your answer is 'Irrational number'.
Hope I helped!
We get tne n-th term with: tn=1/3tn-1
We know that the first term is t1=81, so 81=1/3t*1-1
81=1/3t-1
82=1/3t
82*3t=1
3t=1/82
t=1/82*3=1/246
The second term is: 1/
2*(1/246)*2)-1
We get the third term by replacing n with 3 and so on...
For this case we have that by definition of power properties it is fulfilled that:

Then, if we have the following expression:

Applying the property, we can rewrite the expression as:

Answer:

Answer:
solve for V= pier^/3
solve for R=Square root3Vpie over pie
Step-by-step explanation:
V=multiply 1/3(pier^2)
R= Take root of both sides and solve
