Explain how to solve 4^x+3 = 7 using the change of base formula log base b of y equals log y over log b. Include the solution fo

Masja [62]

The value of x is 1

Explanation:

The equation is $4^x+3=7$

Subtracting both sides by 3, we get,

$4^x=4$

Taking log on both sides, we get,

$\log 4^{x}=\log 4$

Rewriting the equation by $4^{x}=u$

Thus, we have,

$\log u=\log 4$

Applying log rule, if $\log f(x)=\log g(x)$ , then $f(x)=g(x)$

Thus, $u=4$

Substituting $u=4$ in $4^{x}=u$ , we get,

$4^x=4$

Also, since, $a^{f(x)}=a^{g(x)}$ , then $f(x)=g(x)$

Thus, $x=1$

Hence, the value of x is 1

Answer must be in fraction form

Damm [24]

Answer:

-7/18

Step-by-step explanation:

To multiply fractions, you just multiply the top number by the top number and the bottom number by the bottom number. Also, you have to watch the sign.

In this case, we have a positive fraction multiplied by a negative fraction, meaning that our answer must be negative.

So we have- 2x7 / 4x9.

This is simplified to be- 14/36, or 7/18.

However, the answer is actually -7/18, since the number must be negative.

Let me know if this helps.
