Solve for x 64^x^2 = 256^x

Mathematics
1 answer:
kifflom [539]2 years ago
8 0

Answer:

x = 0, 1.333333...

Step-by-step explanation:

1) Convert both sides to the same base.

16^{1.5x^{2} } =16^{2x}

2) Cancel the base of 16  on both sides.

1.5x^{2} =2x

3) Move all terms to one side.

1.5x^{2} -2x=0

4) Factor out the common term x.

x(1.5x-2)=0

5) Solve for x.

1 - Ask: When will x(1.5x-2) equal zero?

When x = 0 or 1.5x - 2 = 0
2 - Solve each of the 2 equations above.

x = 0, 1.333333...

Your father earned​ $34,000 per year in 1984. To the nearest​ dollar, what is that equivalent to in 2014 if the CPI in 2014 is 2
xeze [42]

Answer:

The answer is : 70288.46

Step-by-step explanation:

Your father earned​ $34,000 per year in 1984.

The CPI in 2014 is 215 and the CPI in 1984 is​ 104.

The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.

The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)

34000\times\frac{215}{104} = 70288.46

Answer:

-4.65< -4 and 2/5

Step-by-step explanation:

To solve, this we can convert the fraction -4 and 2/5 into a decimal so that the values can be more easily compared. When we do this, we get the result that -4 and 2/5 equals -4.4. Now we can clearly see which value is greater because they are written in the same form:

-4.65<-4.4

-4.65<-4 2/5
