Answer:
x = 9.125 and 0.875
Step-by-step explanation:
Given the expression
log (x² + 8) = 1 +log(x)?
This can also be written as;
log (x² + 8) = log 10 +logo(x)
log (x² + 8) = log(10x)
(x² + 8) = (10x)
x² -10x + 8 = 0
Factorize;
x = 10±√(-10)²-4(8)/2
x = 10±√100-32/2
x = 10±√68/2
x = 10±8.25/2
x = 10+8.25/2 and 10-8.25/2
x = 18.25/2 and 1.75/2
x = 9.125 and 0.875
Answer:
9.6667
Step-by-step explanation:
3t=29
Divide each side by 3
3t/3 = 29/3
t = 29/3
Three goes into 29 nine times (3*9 = 27 ) with 2 left over
t = 9 2/3
We know 1/3 = .3 repeating
so 2/3 = .6 repeating
t = 9 .6 repeating
