Question

15.38 x 10-2 in standard form

Answer 1

`15.38 * {10}^( - 2) = 0.1538`

I hope I helped you^_^

Answer 2

15.38x10^-2 isn't proper scientific notation.

The coefficient must be between 1 and 10.

Proper scientific notation would be

1.538 x 10^-1

Convert into standard form:

0.5138 is our answer.

And we're done!

Hope it helps you! :)
