Answer:
38,760,000
Explanation:
To write 3.876 x 10^7 in standard form, you need to move the decimal point to the left or right, depending on whether the exponent is positive or negative. In this case, the exponent is positive, so you need to move the decimal point 7 places to the right.
Starting with 3.876, move the decimal point to the right 7 places to get:
38,760,000
So 3.876 x 10^7 in standard form is 38,760,000.
