Which expression is equivalent?

nikitadnepr [17]

Answer:

y⁸/x¹⁰

$\\$

Step-by-step explanation:

$\sf{\large{( \frac{ {x}^{ - 4}y }{ {x}^{ - 9} {y}^{5} } ) ^{2} }}$

$\large{ \sf{= \frac{ {x}^{ - 4 \times 2} {y}^{2} }{ {x}^{ - 9 \times 2} {y}^{5 \times 2} } }}$

$\large{ \sf{= \frac{ {x}^{ - 8} {y}^{2} }{ {x}^{ - 18} {y}^{10} } }}$

$\large{ \sf{ = {x}^{ - 8 - ( - 18)} {y}^{2 - 10} }}$

$\large{ \sf{ = {x}^{ - 8 + 18} {y}^{ - 8} }}$

$\large{ \sf{ = {x}^{10} {y}^{ - 8} }}$

$\large{ \sf{ = \frac{ {x}^{10} }{ {y}^{8} } }}$

$\large{ \sf{ = \frac{ {y}^{8} }{ {x}^{10} } }}$

Selena buys 4 peaches that weigh 1 pound in all. Each peach weigh the same amount. Peaches are on sale for $2.24 per pound. Writ

DENIUS [597]

Answer:

The required equation is

4p = 2.24

And p = 0.56 [ where p is in $]

Step-by-step explanation:

Given that Selena buys 4 peaches that weight 1 pound in all.

Peaches are on sale for $2.24 per pound.

Since the total weight of peaches is 1 pound.

So the price of 4 peaches is $2.24.

Let p be the price of 1 peaches.

Then the price of 4 peaches is $(4×p)

= $4p

According to the problem,

4p = 2.24

$\Rightarrow p=\frac{2.24}{4}$

⇒p=0.56 [ where p is in $]

The required equation is

4p = 2.24

And p = 0.56 [ where p is in $]
