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.

I need help with this
Ilia_Sergeevich [38]

Answer:

1. x= 12.20

2. x= 8.94

3. x= 31.80

Step-by-step explanation:

1.

H =x , P = 7 and B = 10

using pythagoras theorem

H = 12.20

2.

H =21 , P = x and B = 19

using pythagoras theorem

P = 8.94

3.

H =x , P = 15.09 and B = 28

using pythagoras theorem

P = 31.80

Plz help! It’s not hard I just don’t properly understand
jonny [76]

Answer:

a_{13}=2(13)+13=39

39 is the 13th term

Step-by-step explanation:

Okay so essentially the a_n is just a substitute for x.

See how in the equation they put n into the x spot:

y=mx+b\\a_n=mn+b\\a_n=2n+13

They changed the variable names:

y=a_n\\m=2\\n=x\\b=13

Now we know what the n actually means, plus when they ask about the terms youre trying to find it's based off of that n:

When they say, 13 term, they mean a_{13} which would be the 13th answer in the series.  So the first term would be based off of a_1

a_1=2(1)+13\\a_1=15

So whatever number is in the n position by a is what you'll be plugging into the x spot.

y=mx+b\\a_n=2n+13\\a_1=2(1)+13=15\\a_2=2(2)+13=17\\a_3=2(3)+13=19\\a_4=2(4)+13=21\\a_5=2(5) +13=23\\a_6=2(6)+13=25\\a_7=2(7)+13=27\\a_8=2(8) +13=29\\a_9=2(9)+13=31\\a_{10}=2(10)+13=33\\a_{11}=2(11)+13=35\\a_{12}=2(12)+13=37\\a_{13}=2(13)+13=39

These are all the answers leading up to the 13th term they asked for, and you can continue thus same equation with whatever number you can put into the n space.
