Can someone help me? I don’t understand how to do this.

x=8

Step-by-step explanation:

try

x = 32.5

Step-by-step explanation:

12 + 2x −1 = 4

2x −1 +  12 = 4

Step 1: Add -12 to both sides.

2x − 1 + 12 + −12 = 4 + −12

2x −1 = −8

Step 2: Solve Square Root.

2x − 1 = −8

2x − 1 = (−8)^2     (Square both sides)

2x − 1 = 64

2x − 1 + 1 = 64+1   (Add 1 to both sides)

2x=65

2x/2 = 65/2        (Divide both sides by 2)

x = 65/2

x = 32.5

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
