Question

А) 1/3*1/3*1/3*1/3 б)( -1,3)*(-1,3)*(-1,3) в) (-3/5)*(-3/5)*(-3/5)*(-3/5)*(-3/5)

Answer 1

А) 1/81

б)-2, 197

в)-243/3125

Answer 2

Let's calculate each expression:

А) 1/3 * 1/3 * 1/3 * 1/3

To multiply fractions, you simply multiply the numerators together and multiply the denominators together:

1/3 * 1/3 = (1 * 1) / (3 * 3) = 1/9

1/9 * 1/3 = (1/9) * (1/3) = (1 * 1) / (9 * 3) = 1/27

So, the result is 1/27.

Б) (-1.3) * (-1.3) * (-1.3)

Multiplying negative numbers together follows the same rule as positive numbers:

(-1.3) * (-1.3) = 1.69 (rounded to two decimal places)

1.69 * (-1.3) = -2.197 (rounded to three decimal places)

So, the result is approximately -2.197.

В) (-3/5) * (-3/5) * (-3/5) * (-3/5) * (-3/5)

Similarly, to multiply fractions, multiply the numerators together and multiply the denominators together:

(-3/5) * (-3/5) = (3 * 3) / (5 * 5) = 9/25

(9/25) * (-3/5) = (9 * -3) / (25 * 5) = -27/125

(-27/125) * (-3/5) = (-27 * -3) / (125 * 5) = 81/625

(81/625) * (-3/5) = (81 * -3) / (625 * 5) = -243/3125

So, the result is -243/3125.

If you prefer a decimal approximation, it would be approximately -0.07776 (rounded to five decimal places).
