Then put 10/20, simplify, and you have yourself 1/2.
Answer:
41 -12√5
Step-by-step explanation:
- All square roots of natural numbers, other than of perfect squares, are irrational.
so, let the unknown irrational number be x,
solve:
√x + √5 = 6
√x = 6 - √5
( √x ) ² = ( 6 - √5 )²
x = ( 6 - √5 )( 6 - √5 )
x = 36 -6√5 -6√5 + 5
x = 41 -12√5
