1: answer: 4^6 ( reduce the fraction with 4^3)

2: answer: 1 ( any nonzero expression raised to the power of 0 equals 1 )

3: answer 3^8
steps: (3^2)^4 = 3^2×4 ( to raise a power to another Power multiply the exponents)
3^2×4 = 3^8 ( multiply the 2 and the 4 exponent to get a 8 as a exponent )

Por lo tanto el número es p/q = 8/64.

<h3>¿Qué es una fracción?</h3>

Fracción es un número que se puede representar en forma de p/q, donde q no es igual a cero.

It is given that :

En su forma más simple, el número es 1/8

Sea el número p/q

p + q = 72 (dado)

p/q = 1/8

q = 8p

p+8p = 72

9p = 72

p = 8

q = 8p

q = 8 * 8 = 64

Por lo tanto el número es p/q = 8/64.

What is an equation of a circle whose center is at (2,-4) and is

Evgesh-ka [11]

The equation of the circle with center at (2,-4) and tangent to the line x = -2 is given by:

(2) (x - 2)² + (y + 4)² = 16

<h3>What is the equation of a circle?</h3>

The equation of a circle of center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

The circle has center at (2,-4), hence $x_0 = 2, y_0 = -4$ .

The center is tangent to the line x = -2, hence it has a point at x = -2, since |-2 - 2| = 4, r = 4 -> r² = 16.

Hence the equation of the circle is given by:

(2) (x - 2)² + (y + 4)² = 16

If the train from Milan, Italy, to Rome, Italy, takes 6 hours at a speed of 130 miles per hour, how many miles from Milan is Rom

Fittoniya [83]

Step-by-step explanation:

the speed is 130 miles / hour.

that means the train travels 130 miles in 1 hour.

so, the question is, how far is it traveling. when it is going with that speed for 6 hours ?

well, 130 × 6 = 780 miles.

formally, speed is "distance / time".

multiplying this by some time, we have then an expression of "(distance / time) × time", which is then simply "distance".

5.4x 7 \4 simplify this wat do i do ?????

Artyom0805 [142]

Hey there!☺

$Answer:\boxed{9.45}$

$Explanation:$

$5.4\times\frac{7}{4}$

Multiply 5.4 by 7:

$5.4\times7=37.8$

Now divide 37.8 by 4:

$37.8/4=9.45$

$9.45\text{ is your answer.}$

Hope this helps!☺

Solve for x. (e^x-e^-x)/((e^x+e^-x)=t

Sergio [31]

$\dfrac{e^x-e^{-x}}{e^x+e^{-x}}=t\\\\
\dfrac{e^{2x}-1}{e^{2x}+1}=t\\\\
e^{2x}-1=t(e^{2x}+1)\\\\
e^{2x}-1=e^{2x}t+t\\\\
e^{2x}-e^{2x}t=t+1\\\\
e^{2x}(1-t)=t+1\\\\
e^{2x}=\dfrac{t+1}{1-t}\\\\
e^{2x}=-\dfrac{t+1}{t-1}\\\\
2x=\ln\left(-\dfrac{t+1}{t-1}\right)\\\\
x=\dfrac{\ln\left(-\dfrac{t+1}{t-1}\right)}{2}\qquad t\in(-1,1)
