Let us assume 2​1​ is rational. So we can write this number as 2​1​=ba​ ---- (1) Here, a and b are two co-prime numbers and b is not equal to zero. Simplify the equation (1) multiply by 2​both sides, we get 1=ba2​​Now, divide by b, we get b=a2​ or ab​=2​Here, a and b are integers so, ab​ is a rational number, so 2​ should be a rational number. But 2​ is a irrational number, so it is contradictory. Therefore, 2​1​ is irrational number

From formula , Area of sector = 1/2×l.r

Pushpa Chauhan 5 years, 1 month ago

area of sector = ?,radius= r, length=l. Arc length= theta/360 *2πr l=theta/180*πr area of sector=theta/360*2πr^ we write as area of sector= theta/2*180*πr*r = (theta /180*πr)*r/2 =l*r/2 ans
