A

Rounding Without Exponent Adjustment

1

Round each number to a single-digit coefficient times a power of 10 and enter the resulting coefficient.

1

8.0×10128.0 \times 10^{12}

2

7.1×10107.1 \times 10^{10}

3

B

Rounding With Exponent Adjustment

1

Round each number to a single-digit coefficient times a power of 10. Some coefficients round up to 10, which requires adjusting the exponent. Enter the resulting exponent.

1

9.6×10−69.6 \times 10^{-6}

2

9.8×1039.8 \times 10^{3}

3

9.6×1029.6 \times 10^{2}
