10=90(1/2)^x
We move all terms to the left:
10-(90(1/2)^x)=0
Domain of the equation: 2)^x)!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
-(90(+1/2)^x)+10=0
We multiply all the terms by the denominator
-(90(+1+10*2)^x)=0
We calculate terms in parentheses: -(90(+1+10*2)^x), so:x=0/1
90(+1+10*2)^x
We add all the numbers together, and all the variables
9021^x
Back to the equation:
-(9021^x)
x=0
