Please please please help

Answer 1

The answer is ⇒ (0 + 3) + (1 + 3) + (4 + 3) + (9 + 3)

Explanation:

∑ n² + 3 from n = 0 to m = 3 means

n = 0 ⇒ (0)² + 3 = (0 + 3)

n = 1 ⇒ (1)² + 3 = (1 + 3)

n = 2 ⇒ (2)² + 3 = (4 + 3)

n = 3 ⇒ (3)² + 3 = (9 + 3)

∑ ⇒ add all of them

∴ The answer is ⇒ (0 + 3) + (1 + 3) + (4 + 3) + (9 + 3)
