Math Problem Statement

(4 × 10^(-2)) × (6 × 10^5)

Solution

To solve this problem, let's calculate (4×102)×(6×105)(4 \times 10^{-2}) \times (6 \times 10^5) and express the result in scientific notation.

Step-by-Step Solution

  1. Multiply the coefficients (numbers):
    4×6=244 \times 6 = 24.

  2. Apply the properties of exponents:
    102×105=10(2+5)=10310^{-2} \times 10^5 = 10^{(-2 + 5)} = 10^3.

  3. Combine these results:
    24×10324 \times 10^3.

  4. Express in scientific notation:
    Since scientific notation requires a single non-zero digit to the left of the decimal point, we rewrite 24×10324 \times 10^3 as: 2.4×1042.4 \times 10^4

Final Answer

2.4×1042.4 \times 10^4

Would you like further clarification on any of these steps, or do you have any other questions?


Here are some related questions to expand your understanding:

  1. What would happen if one of the exponents was negative and larger in absolute value?
  2. How would you multiply three terms in scientific notation, like (3×102)×(4×101)×(2×103)(3 \times 10^2) \times (4 \times 10^{-1}) \times (2 \times 10^3)?
  3. Can you explain the process for dividing numbers in scientific notation?
  4. How would you convert a number in standard form, like 3500, into scientific notation?
  5. What are some common mistakes to avoid when working with exponents in scientific notation?

Tip: Remember that when multiplying powers of 10, you can add the exponents, and when dividing, you subtract them. This can save time and simplify calculations.
