Verified Answer :

The answer is 2.45 × 10⁵

7(3.5 × 10⁴) = 7 * 3.5 × 10⁴
                   = 24.5 × 10⁴
                   = 2.45 × 10 × 10⁴
                   = 2.45 × 10¹⁺⁴
                   = 2.45 × 10⁵

Answer:

The answer is:

\(2.45\times 10^5\)

Step-by-step explanation:

We are asked to expression the value of the given expression:

\(7(3.5\times 10^4)\) in scientific notation.

We know that any number in scientific notation is expressed as:

So the number is written in two parts:


  • Just the digits (with the decimal point placed after the first digit), followed by
  • × 10 to a power that puts the decimal point where it should be .

Now the value of \(7(3.5\times 10^4)\) is:

\(7(3.5\times 10^4)=7\times 3.5\times 10^4\\\\7(3.5\times 10^4)=24.5\times 10^4\)

in scientific notation the number \(24.5\times 10^4\) is expressed as:

\(2.45\times 10^5\)

Hence, the scientific notation of \(7(3.5\times 10^4)\) is:

\(2.45\times 10^5\)
