Question

1. $(9.3 \times 10^{-5})(2.7 \times 10^{-2})$

Explanation:

Step1: Multiply the coefficients

$9.3 \times 2.7 = 25.11$

Step2: Multiply the powers of 10

$10^{-5} \times 10^{-2} = 10^{-5 + (-2)} = 10^{-7}$

Step3: Combine and adjust to scientific notation

$25.11 \times 10^{-7} = 2.511 \times 10^{-6}$

Answer:

$2.511 \times 10^{-6}$
