Question

(1,8*10^-1)*(4*10^-2)

Answer 1

Ответ:

$0,0072$

Объяснение:

$(1,8*10^{-1})*(4*10^{-2})=(1,8*4)*10^{-1-2}=7,2*10^{-3}=\\=0,0072$

Answer 2

To multiply numbers written in scientific notation, you can multiply the coefficients (numbers) together and add the exponents.

In this case, we have:

(1.8 * 10^-1) * (4 * 10^-2)

Multiplying the coefficients:

1.8 * 4 = 7.2

Adding the exponents:

10^-1 * 10^-2 = 10^(-1 + -2) = 10^-3

Combining the coefficient and exponent:

7.2 * 10^-3

So, (1.8 * 10^-1) * (4 * 10^-2) is equal to 7.2 * 10^-3.
