Question
On 21st January 2021, NASA shared photos of the huge
galaxy cluster. What statement is INCORRECT about the cluster? 1. The cluster is older and slower galaxy cluster merge than the Bullet Cluster. 2. Name of the cluster is Abell 370 and was first discovered in 2002 using the lensing effect. 3. Cluster is located 4.9 billion light – years away from the Earth in the constellation Cetus. Select the correct answer using the code given below.Solution
The correct answer is A
If a + b + c = 9 and ab + bc + ca = 20, then find the value of a² + b² + c².
- 8p 3 Â - 27q 3 Â - 36p 2 q + 54pq 2 Â is equivalent to:
If, ( a + b = 12 ) and ( a² + b² = 80 ), then find the value of (a³ + b³). Â

- If (510 – 486 + 240) ÷ 8 + √2500 = x, then {(x/2) + 18} = ?
(u - 5) 2 + (v + 2) 2 + (w – 4) 2 = 0, then find the value of 4u - v + w.
Given that x = 80, y = -35 and z = -45, Determine the value of [(x³ + y³ + z³)/10³]
If (x –4)3+(x–5)3+(x–6)3 = 3(x–4)(x–5)(x–6), Then x = ?
When positive numbers x, y and z are divided by 31, the remainders are 17, 24 and 27, respectively. When (4x - 2y + 3z) is divided by 31, the remainder ...
If x² + x = 11
find (x+4)³ +1/((x+4)³)
