Los resultados son los siguientes:

  1. 2097152
  2. \frac{1}{729}
  3. b^{12}
  4. x^{24}
  5. x^{\frac{6}{5} }
  6. 3600
  7. a^{6}\cdot b^{10}\cdot c^{-8}
  8. 200\cdot x^{19}
  9. 108\cdot y^{6}

En este ejercicio debemos aplicar cualesquiera de las siguientes propiedades asociadas a los exponentes:

(i) (a^{b})^{c} = a^{b\cdot c}

(ii) a^{c}\cdot b^{c} = (a\cdot b)^{c}

(iii) a^{-b} = \frac{1}{a^{b}}

(iv) a^{b} = a^{b}, donde a es negativo o positivo y b es par.

(v) (-a)^{b} = -a^{b}, donde a es positivo y b es impar.

(vi) a^{b}\cdot a^{c} = a^{b+c}

A continuación, tenemos los siguientes resultados:

a) (2^{3})^{7} = 8^{7} = 2097152

b) (3^{3})^{-2} = 3^{-6} = \frac{1}{729}

c) (b^{3})^{4}=b^{12}

d) [(x^{2})^{3}]^{4} = (x^{6})^{4} = x^{24}

e) \left(x^{\frac{3}{5} }\right)^{2} = x^{\frac{6}{5} }

f) (3\cdot 4\cdot 2)^{5} = 3^{2}\cdot 4^{2}\cdot 5^{2} = 9\cdot 16\cdot 25 = 3600

g) (a^{3}\cdot b^{5}\cdot c^{-4})^{2} = (a^{3})^{2}\cdot (b^{5})^{2}\cdot (c^{-4})^{2} = a^{6}\cdot b^{10}\cdot c^{-8}

h) (2\cdot x^{5})^{3}\cdot (-5\cdot x^{2})^{2} = (2^{3}\cdot x^{15})\cdot [(-5)^{2}\cdot x^{4}] = (8\cdot x^{15})\cdot (25\cdot x^{4}) = (8\cdot 25)\cdot x^{19} = 200\cdot x^{19}

i) \left(3\cdot y^{\frac{2}{3} }\right)^{3}\cdot (2\cdot y^{2})^{2} = (27\cdot y^{2})\cdot (4\cdot y^{4}) = 108\cdot y^{6}

A cyclist rides her bike at a rate of 12 meters per second. What is this rate in kilometers per hour? How many kilometers will t
IgorLugansk [536]

Answer:

Part 1) The rate is 43.2\frac{km}{h}

Part 2) 129.6\ km

Step-by-step explanation:

Part 1)

we know that

A cyclist rides her bike at a rate of 12 meters per second

Remember that

1 hour=3,600 seconds

1 kilometer=1,000 meters

therefore

12\frac{m}{sec} =\frac{(12/1,000)}{(1/3,600)}=\frac{12*3,600}{1,000}=43.2\frac{km}{h}

Part 2) How many kilometers will the cyclist travel in 3 hours?

using proportion

\frac{43.2}{1}\frac{km}{h}=\frac{x}{3}\frac{km}{h}\\ \\x=43.2*3\\ \\x=129.6\ km

Each big square below represents one whole What percent is represented by the shaded area?
Talja [164]

Answer:

93%

Step-by-step explanation:

There are 100 squares per large square so 200 squares total.

14 of them are in shaded.

200-14= 186

186/200=.93

move the decimal point two to the right to get the percentage out of a number.

.93=93%
