Answer:

Step-by-step explanation:
Well we can use the exponential identity: 
The base must be the same for this to work.
So let's combine like bases: 
We can simplify b^2 * b^3 using this identity to get: b^(2+3) = b^5
This gives us the equation: 
But to take a deeper look as to why this identity holds, let's represent b^2 and b^3 by what it really means:
, so this is really just:
which can be simplified as an exponent:
, hopefully this helps you understand intuitively why this identity makes sense.
So using this identity, we can simplify j^2 * j^4 to j^6
This gives us the equation: 
Answer:
25%
Step-by-step explanation:
1/2 ×1/2
=1/4
=0.25
which is 25%
<span>C = AB + D
AB = C - D
B = (C-D)/A
B = C/A - D/A</span>
3xy
<span>y(3y)/3xy + y(xy)/3xy + (y+1)(3x)/3xy </span>
<span>NOW since all of the fractions have a denominator of 3xy, drop the denominators and solve using the numerators. </span>
<span>y(3y) + y(xy) + (y+1)(3x) </span>
<span>3y^2 + xy^2 + 3xy +3x </span>
<span>cannot simplify further.</span>
