0.00072

The standard form of 2.7*10^-3 is 0.0072

Step-by-step explanation:

A simple way to transforms from the scientific notation to standard form is to locate the significand, 7.2 in this case, without decimals, before or after the number of zeros that the exponent indicates. If the exponent is negative then the significand is located before the zeros following the dot after the first zero. For the positive exponent, the zeros are located after the significand, no dot is added.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
