Answer:
a² + 4ab + 4b²
Step-by-step explanation:
Given
(a + 2b)²
= (a + 2b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis
= a² + 2ab + 2ab + 4b² ← collect like terms
= a² + 4ab + 4b²

Answer:
Step-by-step explanation:
If a be a real number,
Then the product of a and its multiplicative inverse is equal to the multiplicative identity, i.e. 1,
∵ 
Thus, the multiplicative inverse of a is 
By comparing it,
We found that,
The multiplicative inverse of 
is 
i.e.
