Question

find the value of each of the following using the shortcut method 25 cube please solve step by step it is urgent pleaseeeeeeeeeeeeeeeee using this ☝️☝️☝️☝️formula ​

Answer 1

$\red{ Value \:of \: (25)^{3} } \\= ( 20 + 5)^{3} \\= (20)^{3} + 3 \times (20)^{2} \times 5 + 3 \times 20 \times 5^{2} + 5^{3}$

/* __________________

By Algebraic Identity :

$\pink { (a + b)^{3} = a^{3} + 3a^{2}b+ 3ab^{2} + b^{3} }$

_____________________*/

$= 8000 + 6000+ 1500 + 125 \\= 15625$

Therefore.,

$\red { Value \:of \: 25^{3}} \green {= 15625 }$
