A

Multiplication Without Adjustment

1

Multiply each pair of numbers in scientific notation and enter the resulting exponent (every draw here already has a proper coefficient, so no adjustment is needed).

1

(3×1010)(3×109)(3 \times 10^{10})(3 \times 10^{9})

2

(3×103)(1×103)(3 \times 10^{3})(1 \times 10^{3})

3

(2×1010)(1×107)(2 \times 10^{10})(1 \times 10^{7})

4

(2×104)(2×1010)(2 \times 10^{4})(2 \times 10^{10})

5

(3×103)(3×102)(3 \times 10^{3})(3 \times 10^{2})

6

(1×109)(2×1010)(1 \times 10^{9})(2 \times 10^{10})

7

(3×109)(1×102)(3 \times 10^{9})(1 \times 10^{2})

8

(2×105)(2×108)(2 \times 10^{5})(2 \times 10^{8})

B

Multiplication With Adjustment

1

Multiply each pair of numbers in scientific notation. Enter the resulting exponent after adjusting so the coefficient is between 1 and 10 (every draw here needs the adjustment).

1

(6×106)(8×104)(6 \times 10^{6})(8 \times 10^{4})

2

(7×106)(7×105)(7 \times 10^{6})(7 \times 10^{5})

3

(5×107)(6×102)(5 \times 10^{7})(6 \times 10^{2})

4

(6×108)(7×101)(6 \times 10^{8})(7 \times 10^{1})

5

(5×107)(7×106)(5 \times 10^{7})(7 \times 10^{6})

6

(6×107)(8×101)(6 \times 10^{7})(8 \times 10^{1})

7

(7×105)(5×108)(7 \times 10^{5})(5 \times 10^{8})

8

(5×1010)(4×1010)(5 \times 10^{10})(4 \times 10^{10})
