(x²-1)³ with Identities how much it is and also explain pl

use identity (a - b) ^3 = a^3 - b^3 - 3ab (a - b)

here, a = x ^2

b = -1

= (x^2)^3 - (-1)^3 - 3 * x ^2 * -1 ( x^2 - (-1) )

x^6+ 3 x^2 ( x ^2 + 1)

I think this is the answer

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
