Question

What is the result of ((2 × 10'') + (4 × 10°))?

A. (2 × 10')

B. (5 × 10)

C. (0.5 × 10)

D. (2 × 10²)

Answer 1

The result of the expression ((2 × 10³) + (4 × 10°)) is 2004, which in scientific notation is (2 × 10²). Hence, the correct answer is D. (2 × 10²).

Step-by-step explanation:

The student's question is asking for the result of the expression ((2 × 10³) + (4 × 10°)). To solve this, we first need to understand what the exponents signify. The term 10³ means 10 to the power of 3, which is 1000, and 10° means 10 to the power of 0, which is always 1 regardless of the base.

So, we have:

• (2 × 1000) + (4 × 1)

This simplifies to:

• 2000 + 4
• 2004

Finally, we write the result in scientific notation:

• (2 × 10²)

Therefore, the correct answer is D. (2 × 10²).
