For each sentence below, find the value of x that makes each sentence true.

vitfil [10]

ANSWER

1. $x=\frac{1}{2}$

2. $x=1$

QUESTION 1

The first sentence is $(5^{\frac{1}{5}})^5=25^x$ .

Recall that;

$(a^m)^n=a^{mn}$

We simplify the left hand side by applying this property to get;

$5^{\frac{1}{5}\times 5}=25^x$ .

$\Rightarrow 5^{1}=25^x$ .

We now rewrite the right hand side too in an index form to obtain;

$\Rightarrow 5^{1}=5^{2x}$

We now equate the exponents to get;

$\Rightarrow 1=2x$ .

$\Rightarrow \frac{1}{2}=x$

$\Rightarrow x=\frac{1}{2}$ .

QUESTION 2

The second sentence is $(8^{\frac{1}{3}})^2=4^x$

We simplify the left hand side first to get;

$(2^{3\times \frac{1}{3}})^2=4^x$

$2^2=4^x$

We now rewrite the left hand side too in index form to obtain;

$2^2=2^{2x}$

We equate the exponents to get;

$2=2x$

This implies that;

$1=x$

$x=1$

Determine the equation of the inverse of y=-4/x+1 The inverse is y=-a/x-b where a = a0 and b = a1

leva [86]

y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant

-4
y = -4/x + 1 or y = ---------
x+1

I'm going to assume that the latter is what you meant.

1. Interchange x and y, obtaining:

-4
x = --------
y+1

2. Solve this for y, obtaining y+1 = -4/x, or xy + x = -4, or

-x - 4
xy = -x-4, or y = ---------
x

-1 -1 4
3. Replace y with f (x): f (x) = -1 - -----
x

This last result has the correct form.
