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

(112* 5^4)=?
= 5 * 5 *5 * 5,
= 625.
= 112 * 625.
= 70000 is the ans.
= 5 * 5 *5 * 5,
= 625.
= 112 * 625.
= 70000 is the ans.

112=2^4 * 7 / by prime factorisation
112 * 5^4 = 2^4 * 7 * (10/2)^4.
112 * 5^4 = (2^4 * 7 * (10)^4)/2^4 // 2^4 cancelled on numerator and denominator.
112 * 5^4 = 7*10^4 = 70000 ( 7*10000 = 70000).
112 * 5^4 = 2^4 * 7 * (10/2)^4.
112 * 5^4 = (2^4 * 7 * (10)^4)/2^4 // 2^4 cancelled on numerator and denominator.
112 * 5^4 = 7*10^4 = 70000 ( 7*10000 = 70000).

5^4 = 5 * 5 * 5 * 5, 5 * 5 = 25.
So, 25 * 25 = 625 we can split 112 = 100 + 10 + 2 then;
100 * 625 = 62500,
10 * 625 = 6250,
2 * 625 = 1250 and finally answer is 62500 + 6250 + 1250 = 70000.
So, 25 * 25 = 625 we can split 112 = 100 + 10 + 2 then;
100 * 625 = 62500,
10 * 625 = 6250,
2 * 625 = 1250 and finally answer is 62500 + 6250 + 1250 = 70000.

112 x 5^4 = (2^4 * 7) * 5^4
= 2^4 * 5^4 * 7
= (2*5)^4 * 7
= 10^4 * 7
= 70000
= 2^4 * 5^4 * 7
= (2*5)^4 * 7
= 10^4 * 7
= 70000
