Question

evalute using prper indentities:104×96
please give right answer
or i will report the answer​

Answer 1

$\huge104 \times 96 \\ \\ \tt(100 + 4) \times (100 - 4)$

• Identity required : (a+b)(a-b) = a² - b²

$\large \tt = {(100)}^{2} - {(4)}^{2} \\ \large \tt = 10000 - 16 \\ \large \tt = \overline{\underline{9984}}$

Hence,

• 104 × 96 = 9984

Answer 2

$\sf\large\underline\blue{hope\:this\:helps\:u}$

$\sf\large\underline\red{Given:}$

104*96

$\sf\large\underline\pink{to\:find}$

104*96= ?

$\sf\large\underline\green{solution:}$

104 = [100+4]

96= [100-4]

104*96 can be written as

[100-4][100+4]

$\sf\large\underline\blue{remember\:this\:identity}$

(a+b)(a-b) = a²-b²

[100-4][100+4]  = 100² -4²

                          = 10,000-16

[100-4][100+4] =9984

$\boxed{[100-4][100+4] =9984}$

$\sf\large\underline\blue{final\:answer\: is\:9984}$
