Question

1) -4/9x^5y^7 * 6 3/4xy^4

Answer 1

-4/9 · x^5 · y^7 · 6 3/4 ·x · y^4 = (-4/9 · 27/4) · х^(5 + 1) · y^(7 + 4) = -3 · x^6 ·y^11

Answer 2

-4/9x^5y^7*6 3/4xy^4= -4/9x^5y^7*27/4xy^4= -3x^6y^11. Ответ: -3x^6y^11.

Answer 3

To simplify the expression, we can perform the multiplication step by step. Let's start by multiplying the coefficients and then combine the variables:

Step 1: Multiply the coefficients: -4/9 * 6 3/4 = -4/9 * 27/4

To multiply fractions, multiply the numerators together and the denominators together: = (-4 * 27) / (9 * 4) = -108 / 36

Step 2: Reduce the fraction (if possible): Both the numerator and denominator can be divided by 36: = (-108 ÷ 36) / (36 ÷ 36) = -3 / 1 = -3

So, the simplified expression is -3x^5y^7.
