Answer 1

Answer:

$4\times 10^7$

Step-by-step explanation:

The given number,

38,332,521,

For writing the number as the product of a single digit and an exponent of 10,

We need to move decimal left side 7 times,

Thus, the exponent of 10 in the resultant number is 7,

Also, after shifting the decimal left side 7 times the resultant number is 3.8332521,

i.e. $38332521=3.8332521\times 10^7\approx 4\times 10^7$
