8^x=16
\(8^x=16\)
\( \)\(x \times ln8 = ln16\)
\(x= \frac {ln16}{ln8}\)
\(x=1\frac {1}{3}\)
If x is an integer, then - x is positive. Is this true or false. If false, give a counterexample.
{nl} This is wrong. {nl} All numbers with a minus in front of it are negative.
counterexample:
x = 3 is a positive integer. x = - 3.1 is a negative real number.

What is the difference of the expression (10b-12+17a) and (7b+5+3a)
(10b - 12 + 17a) - (7b + 5 + 3a)
= 10b - 12 + 17a - 7b - 5 - 3a
= 3b - 17 + 14a This is the difference.
A crew is made up of 8 men; the rest are women. 66⅔% of them are men. how many people are in the crew
8 : 66 2/3% = x : 100%
x = (8 * 100%) / (66 2/3%)
x = 12
The crew consists of 12 people, 8 men and 4 women.

What is the absolute value for |10p-4| < 34 ?
\(| 10p-4 |<34 \)
\(| p | <\frac{34+4}{10}\)
\(| p | < 3.8\)
\(L = \{| p | \in \mathbb| \mathbb R | <3.8\}\)
\(10 \times 3=30\)
17(x-y) +9(x-y)=???
Einfach addieren.
\(17(x-y) +9(x-y)=26(x-y)\)
Bruch rechnen 1viertel:0,75
\(0,75 = \frac{75}{100}\)
\(\frac{1}{4}:\frac{75}{100} = \frac{1}{4}\times \frac{100}{75} =\frac{100}{300}=\frac{1}{3}\)
how do u get 15/4 with the math problem x/3-1/2=3/4
\(\frac{x}{3}-\frac{1}{2}= \frac{3}{4} \)
\(x =3 \times \left(\frac{3}{4}+\frac{1}{2}\right)\)
\(x = 3 \times 1 \frac {1}{4}\)
\(x= 3 \frac {3}{4} \ das \ sind \ \frac {15}{4}\)
