Ihave to write this in standard form me

Standard form is combining all of the numbers together so it's simpler. Here are the steps:

If we add 4,000,000 and 300,000, that gets us 4,300,000.

If we add 6,000 to 4,300,000, that gets us 4,306,000.

Now we can add 500+7 and that gets us 507. All we need to do now is add 4,306,000+507. That gives us our answer! :)

faulty parallelism is a grammar construction where there is no balance in the parts of a sentence they have a similar meaning but the grammar structure is not equivalent.

the correct version of this faulty parallelism in the sentence is:

jefferson wrote the declaration of independence, and he was the nation's third president.

the problem with the first version is that the sentence:

"jefferson was both the writer of the declaration of independence"

presents jefferson as both a subject and an agent for the verb "write" because if he was "the writer" then the declaration of independence was written by him, besides that fact, the sentence presents a dependent clause.

while the second sentence:

he was the nation's third president.

presents a basic subject+verb+object structure

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in both sentences:

jefferson wrote the declaration of independence, and he was the nation third president.
