Explain how to solve 2^x + 1 = 9 using the change of base formula log base b of y equals log y over log b. Include the solution

elena55 [62]

Answer:

$x=2.170$

Step-by-step explanation:

The given equation is $2^{x+1}=9$ .

We take logarithm of both sides to base 2 to get:

$\log_2(2^{x+1})=\log_29$

Apply the power rule of logarithms to get:

$x+1=\log_29$

We now apply the change of base formula:

$x+1=\frac{\log_{10}9}{\log_{10}2}$

$x+1=\frac{0.9542}{0.3010}$

$x+1=3.1701$

$x=3.1701-1$

$x=2.1701$

To the nearest thousandth, $x=2.170$

M_MLP = x + 31, mZPLK = x + 147, and mZMLK = 164º. Find x. M M Р L K K

Answer:

Step-by-step explanation:

An angle is equal to the sum of the angles into which it is divided.

∠MLK = ∠MLP + ∠PLK

164° = (x +31)° +(x +147)°

164 = 2x +178 . . . . . . collect terms

-14 = 2x . . . . . . . . . . . subtract 178

-7 = x . . . . . . . . . . . . . divide by 2
