Stephen Hamilton · Answer 1

Take the root of both sides and solve.

x = the square root of 7 (X^4=30) over 7

Subtract the square root of 7 (X^4+30) over 7

Not sure if this is correct ...

Serenity Carlson · Answer 2

Solve for x:10 - (7 x^2) / 3 + X^4/3 = 0

Subtract X^4/3 + 10 from both sides: - (7 x^2) / 3 = - X^4/3 - 10

Multiply both sides by - 3/7:x^2 = X^4/7 + 30/7

Take the square root of both sides:Answer: x = sqrt (X^4/7 + 30/7) or x = - sqrt (X^4/7 + 30/7)
