Question

If 4^x + 4^x = 32, then the value of x is equal to

a) 3 b) 2 c) 1 d) 0​

Answer 1

$\huge \underline \frak \pink {★彡 QUESTION彡★}$

=> 4x² + 4x = 32

$\huge \underline \frak \pink {★彡A᭄ɴsᴡᴇʀ彡★}$

=> 4x² + 4x = 32

=> 4x² + 4x - 32 = 0

=> 4(x² + x - 8) = 0

=> 4[ x(

Answer 2

Answer:

x=2

Step-by-step explanation:

4^x+4^x=32

2(4)^x=32

2*(2*2)^x=2*2*2*2*2

2*(2²)^x=2^5

(2)^2x+1=2^5

compare both quantity

2x+1=5

2x=5-1=4

2x=4

x=4/2=2
