AkiBaki is correct 5/5 100%%

Brody is lying don’t believe them. Math whiz is correct with everything.

place a decimal point so that the number is between 1 and 10

Count the digits from there to the end.

840000 = 8.4 x 10^5

if counting to the left, use negative powers.

0.00034 = 3.4 x 10^-4

AkiBaki is correct
