The answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3  after simplification will be

4 x^{6}  y^{-2}

Step-by-step explanation:

To simplify

\frac{4(2x^3 y^4 )^4}{2(2x^2 y^6 )^3} .

Using exponential law the exponents of variables will be added when multiplied as per rule

we get

\frac{4[(2^4)(x^{3\times 4}) ( y^{4\times4} )] }{2[(2^3)(x^{2\times3} ) (y^{6\times3} )]}\\

\frac{4[(16)(x^{12}) ( y^{16} )] }{2[(8)(x^{6} ) (y^{18} )]}\\\\\frac{64x^{12}y^{16}  }{16 x^{6}y^{18}  }

Now by dividing according to exponential rule the exponents of variables will be subtracted as per rule

(\frac{64}{16} ) x^{12-6}  y^{16-18} \\4 x^{6} y^{-2}

So the answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3  after simplification will be

4 x^{6}  y^{-2}

1.In a class of 45 pupils ,21play chess and 23 play cards and 5play both games
Mumz [18]

Step-by-step explanation:

(a)

ii.

21 - 5 = 16 play only chess.

iii.

23 - 5 = 18 play only cards

5 play both.

that is 16+18+5 = 39 that play at least one of these games.

i.

so, 45 - 39 = 6 don't play any of these games.

(b)

we have 16+18 = 34 pupils out of 45 that play exactly one game.

so the probabilty to pick one of them is as usual

desired cases / total cases = 34/45 =

= 0.755555555... ≈ 0.76

The school store marks up the price of all items by 30% before selling to
Readme [11.4K]

Answer:

$65.325 or $65.33

Step-by-step explanation:

When looking for a percentage in a number, you want to multiply that number by the percentage. Remember that all percentages are to the hundreth power, or 0.00. So if you want to find 30% of 50.25, you multiply it by 0.30 or 0.3. After calculating that you will come up with 15.075 as the percentage. Since the store is marking the price up, you add it to the original price. So your equation is 50.25 + 15.075 =?. After calculating that, you get the answer 65.325. That is only half of your answer though because, when dealing with money, you always round to the nearest hundredth. So when you round 65.325, you get 65.33 which should be the correct answer.

How many batches of raisin granola bars can Ines make if she has 8/3 cups of raisins and each batch requires 2/3 cup of raisins?
iren2701 [21]
4 batches:

2/3 • 4 = 8/3

2/3 + 2/3 + 2/3 + 2/3 = 8/3

2/3 = 0.666666666666667

0.666666666666667 • 4 = 2.666666666666667

8/3 = 2.666666666666667
