The log of x cubed times y squared simplified
tresset_1 [31]

Answer:

log(x^{3}y^{2}) = 3 log x+2 log y

Step-by-step explanation:

Step 1:-

using logarithmic formula log(ab)=log a+log b

so given log(x^{3} y^{2} ) = log (x^{3} )+log(y^{2} )

now simplify

                                              = 3 log x+2 log y

<u>Answer:</u>-

log(x^{3}y^{2})= [tex]3 log x+2 log y

A) \frac{x(x+4)}{(2x+4)(2x+3)}
B) 1/4 = 25%
C) 1/8 = 12.5%

Explanation
A) Let x = the number of yellow blocks.  Then x+4 = the number of red blocks, and x+x+4=2x+4 is the total number of blocks.

The probability of choosing a red block first would be
\frac{x+4}{2x+4}
since there are x+4 red blocks out of 2x+4 total blocks.

The probability of choosing a yellow block after the red block would be 
\frac{x}{2x+4-1}=\frac{x}{2x+3}
since there are x yellow blocks, and after 1 is chosen, there are 2x+3 total blocks remaining.

This gives the total probability of 
\frac{x+4}{2x+4}\times \frac{x}{2x+3}=\frac{x(x+4)}{(2x+4)(2x+3)}

B) If there are 6 yellow blocks, there are 6+4=10 red blocks, and 10+6=16 total blocks.
The probability of getting a red block first would be 10/16, and the probability of getting a yellow block after the red block would be 6/15.  Together this gives us
10/16(6/15) = 60/240 = 1/4 = 0.25 = 25%

C) If there are 6 yellow blocks, there are 6+4=10 red blocks, and 10+6=16 total blocks.
The probability of getting a yellow block first is 6/16, and the probability of getting a second yellow block after the first one is 5/15.  Together this gives us
6/16(5/15) = 30/240 = 1/8 = 0.125 = 12.5%
