27x² and 81x⁵
81 = 27*3
x⁵ = x²x³
81x⁵ = 27*3*x²x³= (27x²)*3x³
We can see that 81x⁵=(27x²)*3x³ includes as a factor 27x²,
so GCF is 27x².
Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s
