Question

Is my answer correct friends ?

Answer 1

Answer:

Sorry your answer is wrong mate.

Option D is correct.

Step-by-step explanation:

$p = 2.7 \times {10}^{11} = 0.27 \times {10}^{12} \\ q = 9 \times {10}^{12 } \\ p + q = 0.27 \times {10}^{12} + 9 \times {10}^{12} \\ = (9 + 0.27) \times {10}^{12} \\ = 9.27 \times {10}^{12}$

Hope it helps you.
