Answer:
300,000+40,000+60+7 = 340,067
Step-by-step explanation:
Standard form states that a number written where each digit has a place value according to its position in relation to other digits. This means stating a number in number form.
Now, converting the expanded form of numbers to standard form.
300,000+40,000+60+7 = 340,067
Since, no value is given for the thousands and hundreds place, so we write zeros in these two places.
Therefore, the standard form of the given expanded form is; 340,067
