Question

multiply and write the answer without exponents
(2x10^3)x(3x10^6)

Answer 1

we can multiply 2 by 3, first. it is 6
then 10^3 = 1,000 and 10^6 = 1,000,000. multiply of them

Answer 2

so 6,000,000

Answer 3

6 x 1,000, x 1,000,000 (look how many zeroes are there, 9 right ?)
= 6,000,000,000

Answer 4

ok so 2x3=6 and 10^3+10^6= 10^9

Answer 5

10^3 multiply 10^6, right ?

Answer 6

if u use the property of exponent :
a^m * a^n = a^(m+n)

Answer 7

so, 10^3 * 10^6 = 10^(3+6) = 10^9

Answer 8

ok got it!!
