Hello from MrBillDoesMath!
Answer:
10.5 or 21/2
Discussion:
By "proximity: I thin the questions is to evaluate
(11 3/8) - (7/8) =
11 + (3/8) - (7/8) =
11 - (4/8) =
11 - (1/2) =
(22/2) - (1/2) =
21/2 = 10.5
Thank you,

Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
