Solve the following exponential equations.<br> 10^(x+1) − 10^(x−1) = 1287

Rudiy27

Answer:x=2.114

Step-by-step explanation:

Given

$10^{x+1}-10^{x-1}=1287$

$10\times 10^x-\frac{10^x}{10}=1287$

Let $10^x=y$

$10y-\frac{y}{10}=1287$

$\frac{100y-y}{10}=1287$

$99y=1287\times 10$

$y=\frac{12870}{99}=130$

$10^x=130$

Taking $\log$ both sides

$x\log (10)=\log (130)$

$x=\frac{\log (130)}{1}$

$x=2.114$

3) one half of four times a number plus the quantity of the number and three *

Charra [1.4K]

Answer:

3.5x

Step-by-step explanation:

Put into numbers, [4*x+(3x)]*1/2. You cant completely solve for x in this, as we would need an answer with no variable. But, 4*x=4x, and 4x+3x=7x because we would need to combine like terms. But you still need to cut it in half. Half of 7x is 3.5x, so there ya go!
