A) 2^(x+3)= 4^(2x)
make base number the same
2^(x+3)= 2^2 (2x)
set the exponents equal to eachother
x+3=2 (2x)
x+3=4x
-x both sides
3=3x
÷3 both sides
x=1
b) 16^(1/5)×2^(x)=8^(3/4)
make base same number
2^4 (1/5)×2^(x)=2^3 (3/4)
2^(4/5)×2^(x)=2^(9/4)
set exponents
4/5 +x=9/4
-4/5 both sides
x= 29/20
Answer:
B.The expanded form is (Two-fifths) (two-fifths) (two-fifths).
E.Two-fifths)cubed = StartFraction 8 Over 125 EndFraction
Answer:
what are you talking about
Ok so let’s write out the problem
4x+6=-x+1
We first want to get the x’s on one side and the numbers on the other
4x+6=-x+1
+x. +x
5x+6=1
Now we want to get the 6 over
5x+6=1
-6. -6
5x=5
Divide by 5 to get the x alone
X is equal to 1
Do you need to show work?
