Question

25x^4 64y^4 factories it
​

Answer 1

is there not any symbol between them.......!!! complete the question..

Answer 2

though the question is wrong because there is no sign in between the numbers

but if there is a sign of minus then the answer will be as follows

25x⁴ - 64y⁴

(5x²)² - (8y²)²

a²-b² =(a+b)(a - b)

(5x² - 8y²)(5x²+8y²)

but if there is plus sign then

25x⁴+64y⁴

(5x²)² +(8y²)²
