Question

Simplify this expression and put your final answer in Scientific Notation: 2.7×1053.2×107
(4 points)
Step 1:
Divide
the coefficients.

Step 2:
Add
to simplify the exponents.

Step 3:
Do not change the exponent
to change into Scientific Notation.

Step 4:
8.44 x 10^12
is the simplified answer.

Answer 1

The expression is (2.7 × 10^5)(3.2 × 10^7).

Step 1: Multiply the coefficients: 2.7 × 3.2 = 8.64.
Step 2: Add the exponents: 5 + 7 = 12.

So the product is 8.64 × 10^12 (already in proper scientific notation).

Note: the given 8.44 × 10^12 is incorrect — the coefficients should be multiplied (not divided), and 2.7×3.2 = 8.64, not 8.44.
