Question

question 1 (1 point) solve the following. \\((1.29 \times 10^{-4}) \times (6.43 \times 10^{3})\\) \\(\circ\\) a \\(8.2947 \times 10^{-1}\\) \\(\circ\\) b \\(8.2947 \times 10^{7}\\) \\(\circ\\) c \\(8.2947 \times 10^{-7}\\) \\(\circ\\) d \\(8.2947 \times 10^{1}\\)

Explanation:

Step1: Multiply the coefficients

$1.29 \times 6.43 = 8.2947$

Step2: Multiply the powers of 10

$10^{-4} \times 10^{3} = 10^{-4+3} = 10^{-1}$

Step3: Combine the results

$8.2947 \times 10^{-1}$

Answer:

a. $8.2947 \times 10^{-1}$
