Factorize the following
4a^4+625b^4
By using formula
x^2+2xy+y^2=(x+y)^2
Step by step

expression #3 is not equivalent. the others are.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
