Log(10-4x) = log(10-3x) this means that:

10-4x = 10-3x ===> after solving we find that 4x=3x , that means x = 0

By selling a watch on 400 and 460’. Loss and profit happened respectively.if the loss and profit are equal, find cp.

Maslowich

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.
The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be x
Profit and Lost be y .

According to the Question :-

$:\implies$ 460 = x + y ( Profit)

$:\implies$ 400 = x - y ( Loss)

Adding both :-

$:\implies$ 460 + 400 = x + y + x - y

$:\implies$ 860 = 2x

$:\implies$ x = 860/2

$:\implies$ x = 430

Hence the Cost price of the watch is 430 .

Tbh this question confusing the **** outta me

Answer:

$8^6$

Step-by-step explanation:

Powers are defined as the number of times you multiply a number by itself. For example, 2 to the 3rd power is 2 multiplied by itself 3 times. 2 * 2 * 2 = 8. You also know that if you multiply two powers of the same base, you add the exponent, and if you raise a power to a different power, you multiply the exponents.

e.g:

$2^2\cdot2^2=2^{2+2}=2^4\\(2^2)^3=2^{2\cdot3}=2^6$

Now, we are asking to use grouping to write 2 to the power 18 as a power of 8. We know 2 to the power 8 is 2 to the power 3, so we have the following equation:

$2^{18}=(2^3)^x$

We know this is now 2 to the power 3x = 2 the power 18, and therefore x = 6, because 3 times 6 is equal to 18. Now, we can just simplify 2 to the third as 8 and we now have:

$8^6$
