Which expression is equivalent to (m^8n^−4)^14 ?
umka2103 [35]

Which expression is equivalent to (m^8\times n^-4)^ 1/4

Answer:

m^2/n

Step-by-step explanation:

Given.

I assume this is your expression:

The expression is =(m^{8} \times n^{-4} )^{\frac{1}{4} }

Now simplify the expression by multiplying the power.

=(m^{8\times \frac{1}{4}} \times n^{-4\times \frac{1}{4}}} )

=(m^{2} \times n^{-1} )

=\frac{m^{2}}{n}

So, the expression is equivalent to \frac{m^{2}}{n}

svetlana [45]

Answer:

$3450

Step-by-step explanation:

Here, P = $3000, N = 1.5 years, R = 10%

SI = \frac{PNR}{100}  \\  \\ SI = \frac{3000 \times 1.5 \times 10}{100}   \\  \\ SI = 450 \\  \\

Amount of down payment

= $3000 + $450

= $3450

joja [24]

Hey!

---------------------------------------------

Solution:

Find the Highest Common Factor of 8, 12, and 20.

Highest Common Factor = 4

Divide.

8 / 4 = 2

12 / 4 = 3

20 / 4 = 5

4 symbolizes the amount of baskets there are.

---------------------------------------------

Answer:

2 banana's per basket.

3 apple's per basket.

5 orange's per basket.

---------------------------------------------

There is no possible way that there can be the same amount of fruit in each basket.
