What is index form?

Index form is defined as the power or exponent which is raised to a number or a variable.

For example, in number 5^2, 2 is the index of 5.

Indices is the plural form of index.

To add index forms, we need to note the following:

• Both the exponents and variables should be same
• Add the coefficients of the variables leaving the exponents unchanged.
• Only terms that have same variables and powers are added

Given:

(3.012 x 10−8) + (4 x 10−8)

3. 012 + 4 (10^-8)

7. 012 × 10^-8

Thus, the sum is 7. 012 × 10^-8. Option C
