ANSWER

{2}^{ \frac{9}{10} }

EXPLANATION

The given expression is

\sqrt[5]{4}  \times  \sqrt{2}

Recall that:

\sqrt[n]{ {a}^{m} }  =  {a}^{ \frac{m}{n} }

\sqrt[5]{ {2}^{2} }  \times  \sqrt{ {2}^{1} }

\sqrt[5]{ {2}^{2} }  \times  \sqrt{ {2}^{1} }  =  {2}^{ \frac{2}{5} }  \times   {2}^{ \frac{1}{2} }

Recall that:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We now apply this property of a exponents to obtain:

\sqrt[5]{ {2}^{2} }  \times  \sqrt{2}  =  {2}^{ \frac{2}{5} +  \frac{1}{2} }  =  {2}^{ \frac{9}{10} }

6x+8y=30
weeeeeb [17]
First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.
