Hello there!

$5700 =>5.7x10^{3}$

Keep in mind that the coefficient must be between 1 and 10.

The positive exponenet means we move the decimal point to the right.

$0.00643 => 6.43x10^{-3}$

The negative exponent means we move the decimal point to the left. Hope this helps. PLEASE  mark Brainliest!
