help please with this problem.

True or false?

4. [(a + 1) / (a + 1) 2] 2 = (a + 1) 4

16 = 4 a + 4 (for a!=-1)

Solution:

a = 3

Si el 2 y el 4 son exponentes, debes indicar esto con ^.

Por ejemplo, x² significa x².

La ecuación es falsa.

[(a+1)/(a+1)²]² = [1/(a+1)]²

[(a+1)/(a+1)²]² = (a+1)⁴ si y solo si a = 0.

If it is [(a + 1) / (a + 1)^2]^2 = (a + 1)^4,

LS: [(a + 1) / (a + 1)^2]^2 = (1/(a + 1))^2 = 1 / (a + 1)^2

False
