add 3.2 x 10^4 and 1.95 x 10^6 in scienitific notation

1 answer

In scientific notation, the first number can be expressed as 3.2 × 10^4 and the second number can be expressed as 1.95 × 10^6.

To add these two numbers, we need to make sure both numbers have the same exponent.

We can convert 3.2 × 10^4 to 32 × 10^3 by moving the decimal one place to the right.

Now we have 32 × 10^3 + 1.95 × 10^6.

Since the exponents are now the same, we can add the coefficients:

32 + 1.95 = 33.95.

Therefore, the sum of 3.2 × 10^4 and 1.95 × 10^6 in scientific notation is 33.95 × 10^3 (or 3.395 × 10^4).
