Which expression is NOT equivalent to a · c · 5 · 5?<br> 10ac <br> 25ac <br> 25ca
arsen [322]

Answer:

10ac

Step-by-step explanation:

We have been given the expression a · c · 5 · 5

We can multiply 5 with 5 and get 25.

Thus, the expression becomes

a · c · 5 · 5= ac25

We can rewrite the expression using commutative property

25ac = 25ca

Therefore, the given expression is equivalent to  25ac and  25ca.

Hence, 10ac is not the correct form.

First option is correct.

Which is the value of this expression when j = negative 2 and k = negative 1?
Natalija [7]

Answer:

Option A.

Step-by-step explanation:

It is given that

j=-2, k=-1

The given expression is

\left(\dfrac{jk^{-2}}{j^{-1}k^{-3}}\right)^3

Substitute the given values in the above expression.

\left(\dfrac{(-2)(-1)^{-2}}{(-2)^{-1}(-1)^{-3}}\right)^3

\Rightarrow \left(\dfrac{(-2)(1)}{\dfrac{1}{-2}(-1)}\right)^3

\Rightarrow \left(\dfrac{-2}{\dfrac{1}{2}}\right)^3

\Rightarrow \left(-4\right)^3

\Rightarrow -64

Therefore, the correct option is A.
