Question

1.95 ✕ 106 + 32.8
Show work in scientific notation.

Answer 1

1.95 ✕ 10^6 + 32.8 = 1.95 ✕ 10^6 + 32.8 ✕ 1 ✕ 10^0

Now, we need to convert 32.8 to scientific notation:

32.8 = 3.28 ✕ 10^1

Substituting this value back into the expression:

1.95 ✕ 10^6 + 3.28 ✕ 10^1 ✕ 1 ✕ 10^0

Simplifying, we add the exponents:

1.95 ✕ 10^6 + 3.28 ✕ 10^1 ✕ 10^0 = 1.95 ✕ 10^6 + 3.28 ✕ 10^1 ✕ 10^0
= 1.95 ✕ 10^6 + 3.28 ✕ 10^1 ✕ 10^0
= 1.95 ✕ 10^6 + 3.28 ✕ 10^1
= 1.95 ✕ 10^6 + 32.8

Therefore, the sum in scientific notation is 1.95 ✕ 10^6 + 32.8.
