Answer:

Option 3 -  1.3E-2=0.013

option 4 -   1.3E-2=1.3\times 10^{-2}

Step-by-step explanation:

Given : Kory calculated several numbers in his calculator. The result displayed 1.3E-2 on the calculator screen.

To find : Which equivalent number(s) does this represent?

Solution :

The result displayed 1.3E-2 on the calculator screen is written in scientific notation where E represents 10 to the power.

So, We can write 1.3E-2 in standard notation,

1.3E-2=1.3\times 10^{-2}

or 1.3E-2=\frac{13}{10}\times \frac{1}{100}

1.3E-2=0.013

Therefore, Option 3 and 4 are equivalent.
