Question

Interpreting a Technology Solution

Find the quotient of 2.5 × 10-3 and 7.1 × 106. What can be concluded about the solution? Check all that apply.

The E indicates that the solution is given in scientific notation.

The coefficient is 3.5211.

The exponent is 10.

The solution can be written in scientific notation as 3.5211 × 10-10.

The solution is 35,211,000,000.

Answer 1

Compute: (2.5 × 10^-3) ÷ (7.1 × 10^6) = (2.5/7.1) × 10^(-3-6) = 0.352112676… × 10^-9 = 3.52112676… × 10^-10 ≈ 3.5211 × 10^-10.

Now the statements:
- The E indicates that the solution is given in scientific notation. — True.
- The coefficient is 3.5211. — True (rounded coefficient).
- The exponent is 10. — False (the exponent is −10).
- The solution can be written in scientific notation as 3.5211 × 10^-10. — True.
- The solution is 35,211,000,000. — False.
