Answer:
We have the value as 3m-7
Step-by-step explanation:
It is given that we have the real number m. Now we are required to find the simplified form or the value of the expression: 
Thus we can write it as:

Here we have to use the property:

So now we have:

So this is the required final value of the expression.
Answer:
Step-by-step explanation:
log3^(2x+3) = log243
(2x+3)log3 = log243
2x+3 = log243/log3
2x = (log243/log3)-3
x = [(log243/log3)-3]/2
x = (5-3)/2
x = 2/2
x = 1
Check:
3^2(1)+3 = 243
3^2+3 = 243
3^5 = 243
3×3×3×3×3 = 243
9×9×3 = 243
81×3 = 243
243 = 243

Step-by-step explanation:
JK intercept line XY at the midpoint. This means that these points are all equidistant from the midpoint. Due to this, J and K are both an equal distance from M. So is X and Y.
