Question

(1,2*10^-3)*(7*10^-2)

Answer 1

.........,...............

Answer 2

To multiply two numbers in scientific notation, you can multiply their coefficients and add their exponents. Let's calculate the result of (1 * 2 * 10^-3) * (7 * 10^-2):

Coefficient multiplication: (1 * 2) = 2 Exponent addition: (-3 + -2) = -5

So, the result is 2 * 10^-5. In standard decimal notation, this is equal to:

0.00002

Therefore, (1 * 2 * 10^-3) * (7 * 10^-2) = 0.00002.
