We can write an equivalent expression by factoring this polynomial.

Since the GCF for these terms is 5, we can factor out a 5.

That leaves us with each term divided by 5 inside the parenthses.

So we have 5(x + 3).

Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6. explain Andrea’s mistake and give the correct answer

Dvinal [7]

Answer:

Correct answer = $1.35\times10^{12}$

Step-by-step explanation:

Given:

Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6.

Question asked:

Explain Andrea’s mistake and give the correct answer.

Solution:

The above question is of <u>exponential question</u>:

Here Andrea simply <u>added </u>6.75 to 0.2 and got 6.95 and took 10^6 as common and written down wholly 6.95 x 10^6 which is incorrect.

Here we <u>multiply</u> 6.75 to 0.2 and get 1.35 and secondly to multiply 10^6 with 10^6 we have to understand the rule of exponents:-

<u></u> $a^{m} \times a^{n} =a^{m+n}$

$Similarly,\ 10^{6} \times 10^{6}=10^{6+6}=10^{12}$

Hence when we multiplied 6.75 x 10^6 and 0.2 x 10^6 originally we got $1.35\times10^{12}$
