Answer 1

Ответ:

10,125.

Объяснение:

27(-3^2а^3):(3^5а^-1)^3 при а=-0,1

27(-18а):(-16a)3

-486а:(-48а)

При а=(-0,1): -486(-0,1):48^0,1

При  а=(-0,1): 48,6:4,8

При а=(-0,1): 10,125.

Ответ: 10,125

Answer 2

To evaluate the expression, let's substitute the value of "a" into the given expression and perform the calculations step by step.

Given expression: 27(-3^2a^3) / (3^5a^-1)^3

Substituting a = -0.1:

= 27(-3^2(-0.1)^3) / (3^5(-0.1)^-1)^3

= 27(-3^2 * (-0.1)^3) / (3^5 * (-0.1)^-1)^3

Now let's simplify the numerator and the denominator separately.

Numerator: = 27(-3^2 * (-0.1)^3) = 27(-9 * (-0.001)) = 27(0.009) = 0.243

Denominator: = (3^5 * (-0.1)^-1)^3 = (243 * (-10)) ^ 3 = (-2430) ^ 3

To find the value of (-2430)^3, we multiply -2430 by itself three times:

= -2430 * -2430 * -2430 = 14,809,590,000

Now we can substitute these values back into the expression:

= 0.243 / 14,809,590,000

This is the simplified value of the expression when a = -0.1.
