<h3>Answer:   k = 6+10x</h3>

=======================================================

Work Shown:

64*4^{5x}\\\\\left(2^6\right)*\left(2^{2}\right)^{5x}\\\\\left(2^6\right)*\left(2^{2*5x}\right)\\\\\left(2^6\right)*\left(2^{10x}\right)\\\\2^{6+10x}\\\\

The result is in the form 2^k with k = 6+10x

------------------------

Explanation:

First we need to get everything as an exponential expression with a base 2.

We rewrite 64 as 2^6 and 4 as 2^2 in the second step.

In the third step, I used the rule (a^b)^c = a^{b*c} which says to multiply the exponents together. That's how I went from (2^2)^{5x} to 2^{2*5x}. Then the 2*5x in the exponent becomes 10x.

To wrap things up, I used the rule a^b*a^c = a^{b+c} which says to add the exponents when we multiply stuff of the same base together.

Toms house cost $100000 in the year 2000 in 2008 he sold his house for 125000 what was the percentage of change in the price of
Leno4ka [110]
There was a 125% change in the price of the house.

The changed price was an increase of from the original 100,000 therefore the answer can be concluded to be above 100%.

Anyways, to solve this problem you need to find what 125,000 is OF 100,000, meaning you need to divide. 125,000/100,000=1.25. 1.25 can then be changed into 125%.
