Question

Алгебра 8 класс сравнить 0,6 x 10^-3 и 6,2 x 10^-4

Answer 1

Запишем их в стандартном виде и только потом сравним:
6 x 10^-4 < 6,2 x 10^-4.

Answer 2

To compare the numbers 0.6 x 10^-3 and 6.2 x 10^-4, we need to make their exponents equal, then compare their coefficients. Both numbers have different exponents in scientific notation, so let's convert them to have the same exponent:

0.6 x 10^-3 = 0.6 x 10^-3 x (10 / 10) = 0.6 x 10^-3 x 10^-1 = 0.6 x 10^(-3 - 1) = 0.6 x 10^-4

Now, we have:

0.6 x 10^-4 (after converting the first number) 6.2 x 10^-4 (second number)

Now, we can compare the coefficients:

0.6 < 6.2

Therefore, 0.6 x 10^-3 is less than 6.2 x 10^-4.
