Call an integer n>1n>1 radical if 2n−12^{n}-1 is prime. What is the 20th smallest radical number? If AA is your answer, and SS is the correct answer, you will get max(25(1−|A−S|S),0)\max \left(25\left(1-\frac{|A-S|}{S}\right), 0\right) points, rounded to the nearest integer.
Plain-text mathematical notation (without MathML)
Call an integer n>1 radical if 2^(n)−1 is prime. What is the 20th smallest radical number? If A is your answer, and S is the correct answer, you will get max(25(1−(|A−S|)/(S)),0) points, rounded to the nearest integer.
Original LaTeX notation
Call an integer $n>1$ radical if $2^{n}-1$ is prime. What is the 20th smallest radical number? If $A$ is your answer, and $S$ is the correct answer, you will get $\max \left(25\left(1-\frac{|A-S|}{S}\right), 0\right)$ points, rounded to the nearest integer.
