Question

(6,3 · 10− 2)(2 · 10− 3)

Answer 1

(63-2)(20-3)
61(20-3)
61•17
1037

Answer 2

To multiply these two numbers in scientific notation, you multiply the coefficients and add the exponents.

$(6.3 \times 10^{-2}) \times (2 \times 10^{-3})$

First, multiply the coefficients:

$6.3 \times 2 = 12.6$

Then, add the exponents:

$10^{-2} \times 10^{-3} = 10^{(-2 - 3)} = 10^{-5}$

Putting it all together:

$12.6 \times 10^{-5}$

So, $(6.3 \times 10^{-2}) \times (2 \times 10^{-3}) = 12.6 \times 10^{-5}$.
