Question
How many stereoisomers does a ketopentose
have?Solution
Stereoisomers are the molecules that have the same molecular formula and differ only in how their atoms are arranged in three-dimensional space . Ketopentose have 4 steroisomers
Simplify:
4x + 6y - [(8x + 5y) - (3x + 2y) + 3y] - 2xIf [8(x + y)3 – 27(x – y)3] ÷ (5y – x) = Ax2 + Bxy + Cy2, then the value of (A2 - 2B + 3C)...
- If (p + q + r) = 10 and (pq + qr + rp) = 30, then find the value of (p² + q² + r²).
√4096 + √(?) + 13 – 29 = 148
If (a - b - c) = 6, and (ab - bc + ca) = 117, then find the value of (a 2 + b 2 + c 2 )
If a² + c² + 17 = 2(a - 8b - 2c²), then what is the value of (a³ + b³ + c³)?
Given that x = 80, y = -35 and z = -45, Determine the value of [(x³ + y³ + z³)/10³]

If 2x+1, x+2, 2 and 5 are in proportion, then what is the mean proportional between 3.5(1-x) and 8(1+x)?
- If [3a + (1/2a)] = 5, then find the value of [9a² + (1/4a²) - 6]
