= (5*5*5*5) 112,
= 625(100 + 10 + 2),
= 62500 + 6250 + 1250,
= 70000.

= (112)*(5^4).
= (2^4*7)*(5^4),
= {(2*5)^4}*7,
= 10^4*7,
= 70000.

Multiplication of a number by 5^n: Put n zeros to the right of the multiplicand and divide the number so formed by 2^n.

So (112 x 5^4) = 1120000/2^4 = 1120000/16 = 70000.

Note: It is only apply for 5^n.

Thank you.

= 112 *(5 power 4).
= 5 power 4 means (5*5*5*5)=625.
= 112 * 625.
= 70,000 simple.
