Question

find the value of 513 square - 512 square.

Answer 1

Answer:

$a^2-b^2 = (a+b)*(a-b)$

$513^2 -512^2 = (513+512)*(513-512)$

$= 1025*1$

$= 1025$

Step-by-step explanation:

$a² - b² = > LHS. LHS$ equals $RHS$, proving that $a2 - b2 = (a + b) (a - b)$.

In the mathematical field known as algebra, abstract symbols rather than   actual numbers are subjected to matrix multiplication and other formal manipulations. The area of mathematics known as geometry investigates how objects are fashioned as well as how they relate to each other and the physical attributes of the space they inhabit. The associative, commutative, and distribute laws are the three basic tenets of algebra. They facilitate the simplicity or solution of problems and aid in illustrating the connection between various number operations.
