ANSWER

The correct answer is

\sqrt[5]{9 {m}^{2}}



EXPLANATION

The given expression is

{(3m)}^{ \frac{2}{5} }


We can rewrite the exponent as


{(3m)}^{ \frac{1}{5} \times 2 }


Or


({(3m)}^{ 2 } )^{ \frac{1}{5} }

We evaluate the inner expression to obtain,


(9 {m}^{2}  )^{ \frac{1}{5} }


We then rewrite as,


\sqrt[5]{9 {m}^{2}}

Nuts.com sells raw almonds for $10 per pound and roasted pistachios for $12 per pound. Christopher spends $70, before taxes and
sp2606 [1]

Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.

Step-by-step explanation:

Cost of almonds per pound = $10

Cost of roasted pistachios = $12

Total amount spent = $70

Weight of nuts = 6.3

Let,

Weight of almonds = x

Weight of roasted pistachios = y

According to given statement;

x+y=6.3   Eqn 1

10x+12y=70   Eqn 2

Multiplying Eqn 1 by 10

10(x+y=6.3)\\10+10y=63\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2;

(10x+12y)-(10x+10y)=70-63\\10x+12y-10x-10y=7\\2y=7

Dividing both sides by 2

\frac{2y}{2}=\frac{7}{2}\\y=3.5

Putting y=3.5 in Eqn 1

x+3.5=6.3\\x=6.3-3.5\\x=2.8

Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.
