Answer:
x = (2 i π n)/log(4) + log(2 sqrt(2))/log(4) for n element Z
Step-by-step explanation:
Solve for x:
2 sqrt(2) = 4^x
Hint: | Reverse the equality in 2 sqrt(2) = 4^x in order to isolate x to the left hand side.
2 sqrt(2) = 4^x is equivalent to 4^x = 2 sqrt(2):
4^x = 2 sqrt(2)
Hint: | Eliminate the exponential from the left hand side.
Take the logarithm base 4 of both sides:
Answer:x = (2 i π n)/log(4) + log(2 sqrt(2))/log(4) for n element Z

Answer:
1 and -1
Step-by-step explanation:
Factoringfind a number set that equals zero and when multiplyed, becomes -1.
1 and -1 multiply to -1 and equal 0,
so x^2-1 turns into (x+1)(x-1)
solve for both x+1=0 and x-1=0
x+1=0
x=-1
x-1=0
x=1
