The answer to your question is: C. 1.4 x 10⁻⁸

Step-by-step explanation:

Change  0.0000000135 to scientific notation

Just move the decimal point 8 points to the right an express the number like

x 10

                1.35 x 10⁸  but we only need two significant figures so 1.4 x 10⁻⁸

A. 1.3 x 10⁻⁷  This option is not correct, we have to move the decimal point one more place to the right

B. 1.3 x 10⁸  This option is not correct because the power must be negative

C. 1.4 x 10⁻⁸ This is the right answer

D. 1.4 x 10⁻⁷      1.4 is correct but the power must be negative
