Question

(6 * 10^-1 )* ( 1,5 * 10 ^4)

Answer 1

(6*10^(-1) )  *  (1.5*10^4) = 6*1.5 * 10^(-1+4) = 9 *10^3= 9000
или 
(6 * 10^(-1))  *  (1.5 *10^4) = (6 *  1/10 ) * 15000= 0.6 *15000 = 9000

Answer 2

To multiply numbers written in scientific notation, you can multiply the coefficients (the numbers before the power of 10) and add the exponents.

In this case, we have:

(6 * 10^-1) * (1.5 * 10^4)

Multiplying the coefficients gives us:

6 * 1.5 = 9

Adding the exponents gives us:

10^-1 + 10^4 = 10^(4-1) = 10^3

Therefore, the result is:

9 * 10^3, or 9,000 in standard notation.
