Question

Calcula valor exacto de E:
E = 3 √5 + 7 π/ 5 - 2 ( √5 - 3 π)

Answer 1

Answer: √5 + 37π/5.

Step-by-step explanation:
To calculate the exact value of E, we can follow the order of operations (PEMDAS):

E = 3√5 + 7π/5 - 2(√5 - 3π)

E = 3√5 + 7π/5 - 2√5 + 6π (distribute the -2)

E = (3√5 - 2√5) + (7π/5 + 6π) (combine like terms)

E = √5 + 37π/5

Therefore, the exact value of E is √5 + 37π/5.
