The computation shows that the value of the indices will be C. 4.2 × 10^5
<h3>How to calculate the value?</h3>
From the information given, the value will be:
= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
It should be noted that in indices when it's multiplication, the powers will be added and subtracted when it's division.
Therefore,
.= (7 × 10³) × (5.4 × 10⁴) / (9 × 10)²
= 4.2 × 10^5
In conclusion, the correct option is C.
