Question

3x10000+7×1000+9×100+0×10+4 is the same:

Answer 1

30000 + 7000 + 900 + 0 + 4

=> 37904

Answer 2

[ you can also write it as ]

3×10,000 + 7×1,000 + 9×100 + 0×10 + 4

= 3×10⁴ + 7×10³ + 9×10²+0×10¹+4×10^0

= 37,904


[ so we can say that ]

3×10,000 + 7×1000 + 9×100 + 0×10 + 4

is same as 37,904
