Answer:
4^5x-1=16
4^5x-1=4²eliminate 4
5x-1=2
5x=2+1
5x=3
x=3/5
log4(10x+2)=1
log4(10x+2)=log4 ⁴
eliminate log4
10x+2=4
10x=4-2
10x=2
x=2/10
x=1/5
difference between the is we use law of indices and logarithm to the questions respectively
similarities is we eliminate there base
Answer:
Step-by-step explanation:
200 = 100%
80 = x%
200x = 8000
x = 40% (percentage increase)
400 = 200%
100 = 50%
500 = 200% + 50%
500 = 250% (the other percentage increase)

Answer:
Step-by-step explanation:
xy=-30
y=-30/x
