$7241 = 7.241 \times 10^{3}$ $7241 = 7.241 xx 10^3$

$7241 = 7.241 \times 10^{3}$ $7241 = 7.241 xx 10^3$

Scientific notation indicates the power of 10

$7000 = 7 \times 1000 = 7 \times 10^{3}$ $7000 = 7 xx 1000 = 7 xx 10^3$

However, it is not exactly 7000, but a bit more which is indicated as a decimal fraction.

$7241 = 7.241 \times 10^{3}$ $7241 = 7.241 xx 10^3$
