Answer:

m^2/n

Step-by-step explanation:

The following laws of exponent are useful to this problem:

\displaystyle \large{ {(mn)}^{b} =  {m}^{b} {n}^{b}   } \\  \displaystyle \large{ {n}^{ - b} =   \frac{1}{ {n}^{b} }    }

We are given the expression:

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } }

Use the first law of exponent above.

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{(8)( \frac{1}{4}) } {n}^{ ( - 4)( \frac{1}{4}) }   } \\  \displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{2 } {n}^{  - 1}   }

Make sure to recall the important necesscary fundamental math such as operation with negative numbers/integers, basic division, fraction, etc.

From the expression, apply the second law of exponent to n^-1.

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{2 } ( \frac{1}{ {n}^{1} } )} \\   \displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{2 } ( \frac{1}{ {n} } )} \\

Multiply m in.

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =   \frac{ {m}^{2} }{ {n} } }

Thus the answer is m^2/n.

How can you find f(2) if f(x)=3x^2-2
Ganezh [65]

Answer:

f(2) = 10

Step-by-step explanation:

Simply just plug in 2 into the equation

f(2) = 3(2)² - 2

f(2) = 3(4) - 2

f(2) = 12 - 2

f(2) = 10

And we have our final answer!
