Answer:
1. A number having 2, 3, 7 or 8 at unit's place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8. The number of zeros at the end of a perfect square is always even. In other words, a number ending in an odd number of zeros is never a perfect square.
2. Only those numbers, when squared will have 6 at their unit place are 4 and 6 Because 4×4 = 16 and 6×6 = 36(i dont know if this is what you were looking for)
3. the square root of 24336 consists of three digits and those digits are 156

Answer:
x = 9√3
y = 18
Step-by-step explanation:
Given the angle measures and given length of the triangle, we can see that this is a 30-60-90 triangle which means the angle measures are 30°, 60° and 90°. A 30-60-90 triangle has special side lengths as indicated in the diagram below. Since the length given is across from the 30° angle, then x = 9.
In this diagram, x = x√3 or 9√3 and y = 2x or 9(2) = 18.
The second option: 4x² - x + 1
All you have to do is add the like terms:
3x² + x² = 4x²
4x - 5x = -x
-2 + 3 = 1
Combine all the results and you will get your solution!
Answer:
4 + 9x² + 1x³ + 12x⁵
Step-by-step explanation:
3x² + 6x² = (3 + 6)x² = 9x²
4 + 3x² + 8x³ + (-7x³ + 12x⁵ +6x²) = 4 + <u>3x² + 6x² </u> + <u>8x³ - 7x³ </u> + 12x⁵
= 4 + 9x² + 1x³ + 12x⁵
