Twelve is six six is three three is five and five is four How?

In Spanish 12 is 4, 4 is 6, 6 is 4 (and 5 is 5); In French 12 is 5, 5 is 4, 4 is 6, 6 is 3 and 3 is 5; In German 12 is 5, 5 is 4 and 4 is 4. Still stuck? Send me a message! well that was a riddle that someone had given me, and the answer wasn't mathmatical..... T W E L V E = six letters S I X = three letters T H R E E = 5 letters F I V E = four letters FOUR = four letters...... so yeah...


-3 plus ln x equals 5?

-3 + ln(x) = 5Add 3 to each side:ln(x) = 8x = e(8) = 2,980.958 (rounded)


How would i simplify e cubed over cube root of e squared multiplied by e to the power of thirteen?

Cube root is the same as to the power of a third; when multiplying/dividing powers of a number add/subtract the powers; when a power is to another power, multiply the powers; as it is all e to some power: e³/(e²)^(1/3) × e^13 = e³/e^(2/3) × e^13 = e^(3 - 2/3 + 13) = e^(15 1/3) = e^(46/3) Which can also be expressed as "the cube root of (e to the power 46)" or "(the cube root of e) to the power 46".
