What the following number in scientific notation: 0.00000089

Answer 1

Scientific notation:

A._____ * 10^x

Example: 3.45 * 10³ is the same as 3450.0

Note that the exponent has been moved 3 places to the right. Remember that moving the decimal point 1 place to the right is the same as multiplying by 10.

We are given 0.00000089

Starting with 8.9, we would have to move the decimal point 7 places to the LEFT. This means

that our answer in scientific notation is 8.9 * 10^-7

This may help with understanding:

0.00xy0 = x.y * 10^-3

0.0xy0 = x.y * 10^-2

0.xy0 = x.y * 10^-1

x.y = x.y * 10⁰ <<remember that n⁰ = 1>>

xy.0 = x.y * 10¹

xy0.0 = x.y * 10²

xy00.0 = x.y * 10³

Answer 2

8.9 x 10^-7

Answer 3

It looks like

8.9 x 10^-7
