Question

(y^4)^5:(y^9)^2*y^3 при у=-1 (z^3)^9:(z^4)^6*a при z=-2 Решите позязя:3

Answer 1

Y^20:y^18*y^3=y^5=-1^5=-1

z^27:z^24*a= z^3*a=-8a

Answer 2

To solve the expressions, let's first evaluate the given values.

1. For y = -1:

Expression 1: (y^4)^5 : (y^9)^2 * y^3

Substitute y = -1: ((-1)^4)^5 : ((-1)^9)^2 * (-1)^3

Now simplify each term inside the parentheses: (1)^5 : (1)^2 * (-1)^3

Further simplify: 1 : 1 * (-1)

Finally: 1 * (-1) = -1

So, the value of the expression with y = -1 is -1.

2. For z = -2:

Expression 2: (z^3)^9 : (z^4)^6 * a

Substitute z = -2: ((-2)^3)^9 : ((-2)^4)^6 * a

Now simplify each term inside the parentheses: ((-8)^9) : (16)^6 * a

Calculate the values: (-134217728) : (16777216) * a

Now, solve the division: a = (-134217728) / (16777216) a = -8

So, the value of the expression with z = -2 is -8.
