#rArr15xx104#

#=15(100+4)#

Answer:

#1560#

Explanation:

#color(blue)(15*104#

Our aim is to use the distributive property to evaluate it faster than the normal method

Distributive property:

#color(brown)(a(b+c)=ab+ac#

Split #104# as #(100+4)#

#rarr15(100+4)#

#rarr15*100+15*4#

#rarr1500+60#

#color(green)(rArr1560#

Hope this helps.. :)
