Answer 1

Answer:

pls make me as brainlist

Answer 2

Step-by-step explanation:

x⁴+81

we cant do anything much with x so the easiest way you can to solve it is think of a number whose ⁴ power is 81, yes its 3 . 3⁴ is 81 so replace it with 81

x⁴+3⁴

now we can write it as

(x²)²+(3²)²

use formula a²+b²= (a+b)²- 2ab

(x²+3²)² - 2x²3²

this is all we can do with this question

i think the more appropriate question should be x⁴-81
