15m (hoch zwei) - 5dm (hoch zwei) + 4000m (auch hoch zwei) = 

\(15m^2 \times \frac{100dm^2}{m^2}-5dm^2 + 4000m^2 \times \frac{100dm^2}{m^2} \) 

\(= 1500dm^2-5dm^2+400\ 000dm^2=401495dm^2\)

y = 3x - 7

hey, its this question : x^2/7-3=20 i dont really know where to start

\(x^{\frac{2}{7} } -3=20\) 

\(x^{\frac{2}{7} } =17\)

\(\frac{2}{7} * ln x = ln 17\)

\(ln x = ln17 * \frac {7}{2}\)

\(x=e^{ln17 * \frac {7}{2}} \)

\(x=20256.8179387\)

??? wat is tgis

3x + 2 = 6x - 2                                    [ - 6x - 2

- 3x = - 4                                              [ / -3 

x = \(\frac {4}{3}\)

kreuze an, um wieviel Prozent die Anzahl der passagiere zwischen 2006 und 2010 ungefähr gestiegen ist:

 40%   50%   60%  70%   80%

in 2006 sind es 705 Passagiere, in 2010 sind es 1219. 

die richtige Antwort ist 70%, aber warum?

705 : 100% = 1219 : x

705x = 100% * 1219

x = 100% * 1219 / 705

x = 172,9%

Die Anzahl der Passagiere ist zwischen 2006 und 2010 um 72,9% gestiegen.

what is 36 x 3/4

\(36 \times \frac {3}{4}= \frac {36 \times 3}{4} = 27\)

if i have 1 chocolate coin that measures from one side of the coin to the other 4 cm and i also have two chocolate coins that measure 3 cm from one side to another tell me witch is bigger the one chocolate coin or the two smaller ones

A1 = (4² * π / 4) = 16 * π / 4

A2 = 2 * (3² * π / 4) = 2 * 9 * π / 4 = 18 * π / 4

A2 > A1

The two chocolate coins are together more than the larger chocolate coin.

(-64)^1/3 x 9^3/2

\((-64)^{\frac{1}{3} } \times 9^{\frac{3}{2} } \) = \(-4 \times 27 = -108\)
