Solve for x using technology 2 log 3(x-1)=log(4 x 2-25)
bagirrra123 [75]
<span>2 log 3(x-1)=log(4 x 2-25)
1.  Determine the domain.  Since the input to the log function cannot be zero or negative, 4x^2-25 must be </span>≥ 0.  Thus, x^2 must be >0, or x>0.  Same domain applies to log (3(x-1); x must be > 0.
2.  Rewrite <span>2 log 3(x-1) as log 3(x-1)^2.
3.  Then we have </span>log 3(x-1)^2 = log(4 x 2-25).  We can discard the operator "log" from both sides:   3(x-1)^2 = 4 x 2-25.  There are various ways in which to solve this.  Since you're supposed to "use technology," 
graph y = 3(x-1)^2 and y = 4x^2 - 25 on the same set of axes.  Determine, using visual estimation or your calculator's tools, the value or values of x that satisfy this equation.  My result was x=3, y =11.

Please solve and explain steps for this problem.
Helen [10]
This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.

(5^49/5^48)+4^0−(1)^79⋅(−3/−4^9)^0
MrMuchimi

Answer:

I believe it is 3.75

Step-by-step explanation:

(5^49/5^48)+4^0−(1)^79⋅(−3/−4^9)^0

5+1−(1)^79⋅(−3/−4^9)^0

5+1−(1)^79

5⋅(−3/−4^9)^0

-3 divided by -4 to the power of 9 to the power of 0=0.75

5 times 0.75=3.75

Hope this is correct! xx
