Perform the following operation:
2.12 × 106 − 3.5 × 105
Advertisements
Solution
To perform an addition/subtraction operation, first, the numbers are written in such a way that they have the same exponent. The coefficients are then added/subtracted.
2.12 × 106 − 3.5 × 105
= 21.2 × 105 − 3.5 × 105
= (21.2 − 3.5) × 105
= 17.7 × 105
= 1.77 × 106
