Question

if 2 to the power x minus 2 to the power xminus 1 equal to 4 , then x to the power x is equal to​

Answer 1

Answer:

2x−2x−1=4

2x−2x2−1=4

2x(1−21)=2x−1=4=22

∴ x−1=2

from this we get   x=3

xx=33=27

Answer 2

Step-by-step explanation:

2^x-2+x-1 = 2^2

=x-2+x-1=2

2x-3 = 2

= 2x= 5

x = 5/2

= 2.5

so , x ^ x = 2.5^2.5
