a) Let's solve your equation step-by-step.
234/16=2k
1073741824=2k
Step 1: Flip the equation.
2k=1073741824
Step 2: Solve Exponent.
2k=1073741824
log(2k)=log(1073741824)(Take log of both sides)
k*(log(2))=log(1073741824)
k=
log(1073741824)
log(2)
k=30
Answer:
k=30
A) =R)
b) (−8/13)−1(16/5)−1(−5/2)−1
=13/−8/(16/5)−1(−5/2)−1
=−13/8/(16/5)−1/(−5/2)−1
=−13/8/5/16/(−5/2)−1
=−26/5(−5/2)−1
=−26/5/2/−5
=−26/5/−2/5
=13
B) =S)
c)
d) (2/7)^-6*(14/9)^-6=4/m)^-6
531441/4096=m6/4096
Step 1: Multiply both sides by 4096.
531441=m6
531441−m6=m6−m6(Subtract m^6 from both sides)
−m6+531441=0
−m6+531441−531441=0−531441(Subtract 531441 from both sides)
−m6=−531441
−m6/−1=−531441/−1
(Divide both sides by -1)
m6=531441
m=±(531441)(1/6)(Take root)
m=9,−9
Check answers. (Plug them in to make sure they work.)
m=9(Works in original equation)
m=−9(Works in original equation)
Answer:
m=9 or m=−9
