You can make it easier by replacing x^n with another variable, factoring, then putting x^n back in the end.
Using exponent and algebra rules, rewrite x^2n - 2x^n + 1 as
(x^n)^2 - (2 x x^2) + 1
Then, let x^n = m.
m^2 - 2m + 1
Now factor that: (m - 1)^2
And now put x^n back: (x^n - 1)^2
Answer:
The answer is 2.5135145
Step-by-step explanation:
- The irrational number between 5,25 and 5,26
- 2.5135145...
- The number is non-terminating and non-recurring. Hence, it is an irrational number.
- A real number that cannot be expressed as a simple fraction is called an irrational number.
- It is impossible to express in terms of a ratio.
- If N is irrational, it is not equal to p/q, where p and q are integers and q is not equal to 0.
- Example: √2, √3, √5, √11, √21, π(Pi) are all irrational.
Answer:
the answer of the expression is 190
Step-by-step explanation:
Given expression as :
20 % of 950
Or, 
times 950
Or, × 950
Or, 20 × 
or, 20 × 9.5
∴ 190
Answer:
The length of shadow decrease at 0.48 m/s.
Step-by-step explanation:
The distance of man from building = x
Thus initially, x = 12
It is given that dx/dt= -1.3 m/s
Let the shadow height = Y
Now solve for the 
when x=4
from the diagram (triangle) it can be seen similar triangles with similar base/height ratios.
