√5 * √5 = 5

hope it helped :)

you will have to be more specific with your question.

15% of what? if you are talking about 15% of 342,000, here how you do it.

when you are adding 15% of a value (342,000) to the value (342,000), you do this. $${\mathtt{342}}{\mathtt{\,\times\,}}{\mathtt{1.15}} = {\frac{{\mathtt{3\,933}}}{{\mathtt{10}}}} = {\mathtt{393.3}}$$

hope this helped :)

You can't solve the algebra when you have two unknown variables.

you will need to know the value of "c" in order to know what the x is.

hope this helped :)

$${\frac{{\mathtt{5}}}{{\mathtt{6}}}} = {\frac{{\mathtt{1}}}{{\mathtt{3}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{d}}$$

$${\mathtt{5}} = {\frac{{\mathtt{1}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{6}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6}}{d}$$

$${\mathtt{5}} = {\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6}}{d}$$

$${\mathtt{5}}{\mathtt{\,-\,}}{\mathtt{2}} = {\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6}}{d}{\mathtt{\,-\,}}{\mathtt{2}}$$

$${\mathtt{3}} = {\mathtt{6}}{d}$$

$${\frac{{\mathtt{3}}}{{\mathtt{6}}}} = {\frac{{\mathtt{6}}{d}}{{\mathtt{6}}}}$$

$${\mathtt{d}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}}$$

First thing you need to do is to make the denominator the same.

you do it by making the denominator as their LCM (Lowest Common Multiple)

since the LCM of 7 and 6 is 42,

$${\frac{\left({\mathtt{1}}{\mathtt{\,\times\,}}{\mathtt{6}}\right)}{\left({\mathtt{7}}{\mathtt{\,\times\,}}{\mathtt{6}}\right)}}{\mathtt{\,\small\textbf+\,}}{\frac{\left({\mathtt{1}}{\mathtt{\,\times\,}}{\mathtt{7}}\right)}{\left({\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{7}}\right)}} = {\frac{{\mathtt{13}}}{{\mathtt{42}}}}$$

I believe in this case x can't be a whole number which means you will have to go through some trial and errors.

when x is 1.5, x^x=1.8371173070873836.... which is obviously smaller than 2

when x=1.6 x^x=2.1212505710975916.... which is bigger than 2

now we know that x is between 1.5 and 1.6

you can always write "x is bigger than 1.5 but smaller than 1.6" or you can do some trial and errors to get more accurate answer such as x=1.559610.....

but i believe you won't be able to get an accurate answer as it is an infinite decimal.

2 times 5 is 10 and you minus 1 from 10 :)
