X² + 10x + 25 = 8
(x + 5)(x + 5) = 8
(x + 5)² = 8
x + 5 = +-√8
x + 5 = +-(√4 × √2)
x + 5 = +-(2√2)

first solution
x + 5 = +2√2
x = -5 + 2√2
x = 2√2 - 5

second solution
x + 5 = -2√2
x = -5 - 2√2
x = -2√2 - 5

The answer is first option and second option

B. 64 ⇒ II. 4 and IV. 8

C. 27 ⇒ I. 3

D. 125 ⇒ V. 5

E. 16 ⇒ II. 4

Step-by-step explanation:

Let us find the correct answer

∵ 121 = 11 × 11

∴ The square root 121 is 11

∴ A. 121 ⇒ III. 11

∵ 64 = 8 × 8

∴ The square root of 64 is 8

∵ 64 = 4 × 4 × 4

∴ The cube root of 64 is 4

∴ B. 64 ⇒ II. 4 and IV. 8

∵ 27 = 3 × 3 × 3

∴ The cube root of 27 is 3

∴ C. 27 ⇒ I. 3

∵ 125 = 5 × 5 × 5

∴ The cube root of 125 is 5

∴ D. 125 ⇒ V. 5

∵ 16 = 4 × 4

∴ The square root of 16 is 4

∴ E. 16 ⇒ II. 4
