Question

43000000*48963200000=?

Answer 1

best way to approach this problem is to convert the numbers into scientific notation

starting with 43000000, we can move the decimal point to the left 7 places to get 4.3, then we multiply this by 10^7. this allows us to re-write the number 43000000 as 4.3*10^7

similar logic with 48963200000 gives us 4.89632 * 10^10

so we can re-write the product as

4.3*10^7 * 4.89632 * 10^10

which is a bit more manageable than the original product. multiply 4.3 * 4.89632, then 10*7 * 10^10 using the exponent rule a^m * a^n = a^(m+n)
