2 mũ x+2 mũ x+2 mũ x+2 mũ x=32

x = 3

Step-by-step explanation:

<=> 2^x + 2^x + 2^x + 2^x = 32

<=> 4x2^x=32

<=> 2^x = 8

<=> x = 3

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
