Answer and explanation

Answer: C. 4

Explanation: Work from the inside: √225 = 15; √(154 + 15) = √169 = 13; √(108 + 13) = √121 = 11; √(25 + 11) = √36 = 6; √(10 + 6) = √16 = 4.

Previous: If a + b + c = 0 (with a, b, c non-zero), find the value of a²/(bc) + b²/(ca)… · Next: If x = 1/(2 − √3), find the value of x³ − 2x² − 7x + 5.
