Question
Consumers have more difficulty evaluating services than
they do products; the difficulty results from the:Solution
Services have few concrete attributes that can be inspected and few standardized specifications that can be compared across alternatives.
If (x + y) = 35, then find the value of (x - 10)6 + (y - 25)6.
- If a 2 + b 2 + c 2 = 240 and ab – bc – ca = 64, then find the value of (a + b – c) 2 .
If a, b and c are integers such that a 2 + b 2 + c 2 = 228, a + b + c = 26 and b = c, then find the value of a?
If ab = -15 and (a2 + b2) = 34, then find the value of (a – b).
If (a + b) = 9 and ab = 14, find the value of (a² + b²).
If, 3x + 2y = 15, and 2xy = 12, and 3x > 2y, then find the value of 27x³ – 8y³.
- If p² + q² + r² = 240 and pq – qr – rp = 64, then determine the value of (p + q – r) ².
- If x² - 2x + 1 = 0, then find the value of (x + x⁻¹)².
