Question

b. Subtract 1.95 x 106 and 3.2 x 104

Answer 1

To subtract 1.95 x 10^6 from 3.2 x 10^4, we can align the numbers by their exponents:

3.2 x 10^4
- 1.95 x 10^6

To subtract, we subtract the coefficients and keep the exponent the same:

3.2 - 1.95 = 1.25

So the coefficient is 1.25. Since 3.2 x 10^4 has a smaller exponent than 1.95 x 10^6, we keep the exponent as 10^4 for our answer.

Therefore, the result of the subtraction is 1.25 x 10^4 in scientific notation.
