Answer:

5.791×10⁷

1.433×10⁹

Step-by-step explanation:

57 910 000.

move the point to the left side then count the number of places it passed

5.7910000 = 7places

1.433000000 = 9places

disregard the zeros replace it by ×10^exponent

if going left = positive exponent

if going right = negative exponent

example:

0.00000051

move to right

= 5.1×10^-⁷
