multiply by 4:
x=8 which is the answer
The angular size of Mars, as seen from the Earth, when it was closest to the Earth is 25 arcseconds.
<h3>What is angular size?</h3>
It should be noted that angular size is the object's apparent size as seen from an observer on Earth.
At its closest approach, the angular size of Mars is 25 arcseconds. This was known through the use of a telescope.

Answer:
6n²√3
Step-by-step explanation:
2√3n•√9n³
The above expression can be simplified as follow:
Recall
√9 = 3
2√3n•√9n³ = 2√3n × 3√n³
Recall
m√a × n√b = mn√(a × b)
Thus,
2√3n × 3√n³ = (2×3) √(3n × n³)
2√3n × 3√n³ = 6√3n⁴
Recall:
√aᵇ = (aᵇ)¹/² = aᵇ/²
√n⁴ = n⁴/²
√n⁴ = n²
Thus,
6√3n⁴ = 6n²√3
Therefore,
2√3n•√9n³ = 6n²√3
