Question

find the value of x so that (3/4)2x±1 =[(3/4)3]3
​

Answer 1

Answer:

x = 4

Step-by-step explanation:

3/4 × 2x + 1 = (3/4 ×3) 3

3/4 × 2x + 1 = 9/4 × 3

3/4 × 2x × 1 = 27/4

2x + 1 = 27/4 ÷3/4

2x + 1 = 9

2x = 9-1

2x = 8

x = 8÷2

x = 4

Answer 2

Answer:

x = 4

Step-by-step explanation:

3/4 × 2x + 1 = (3/4 ×3) 3

3/4 × 2x + 1 = 9/4 × 3

3/4 × 2x × 1 = 27/4

2x + 1 = 27/4 ÷3/4

2x + 1 = 9

2x = 9-1

2x = 8

x = 8÷2

x = 4
