There are infinitely How many pairs of numbers of which the sum of their cube roots is zero give two of these pairs

ivanzaharov [21]

Answer:

Infinite pairs of numbers

1 and -1

8 and -8

Step-by-step explanation:

Let x³ and y³ be any two real numbers. If the sum of their cube roots is zero, then the following must be true:

$\sqrt[3]{x^3}+ \sqrt[3]{y^3}=0\\ \sqrt[3]{x^3}=- \sqrt[3]{y^3}\\x=-y$

Therefore, any pair of numbers with same absolute value but different signs fit the description, which means that there are infinite pairs of possible numbers.

Examples: 1 and -1; 8 and -8; 27 and -27.

How to solve this???<br> e^(2x) - e^x = 6

Ray Of Light [21]

$e^{2x}-e^x=6$
$(e^x)^2-e^x-6=0$
$(e^x-3)(e^x+2)=0$

$e^x=3$
$e^x=-2$

therefore $x=\ln3$ and $x=\ln-2$
because $\ln-2$ doesn't exist, the only solution to your equation is $x=\ln3$

What is the value of f(-16) if f(x)= 2x-16?

Elza [17]

F (x) = f (-16)
So you should plug -16 in for x

f (-16) = 2(-16) -16

f(x) = -32 -16

f(x) = -48
