The sum of the numbers is 2.115 * 10^14

How to evaluate the sum?

The sum expression is given as:

(2.1 × 10^14) + (1.5 × 10^12)

Express 1.5 as 0.015 * 10^2

(2.1 × 10^14) + (0.015 * 10^2 × 10^12)

Evaluate the product

(2.1 × 10^14) + (0.015 * 10^14)

Factor out 10^14

10^14 *(2.1 + 0.015)

Evaluate the sum

10^14 * 2.115

Rewrite as:

2.115 * 10^14

Hence, the sum of the numbers is 2.115 * 10^14
