Question

Find the value of (56.464)² - (46.464)² using standard  identities. 102.928​

Answer 1

Answer:

$(56.464)^2 - (46.464)^2$ = 1029.28

Step-by-step explanation:

$(56.464)^2 - (46.464)^2$

$= (56.464 + 46.464)(56.464 - 46.464)$ [Using the identity $a^2 - b^2 = (a + b)(a - b)$]

= 102.928 x 10

= 1029.28
