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:
(a + b)2 Plug in the a and b values
(2 + 3)2 Add 2 and 3
(5)2 Multiply 5 and 2
10
When a = 2 and b = 3, (a + b)2 will equal 1.) 10.
Answer:
15 and 75
Step-by-step explanation:
complementary - add up to 90 degrees
x+5x=90 degrees
6x=90 degrees
x=90/6
x=15
15*5=75
the 20x(8+2) is just two times greater as its 200 instead of 100 which is the other answer
It is a percent decrease because the original is less than the final value and the answer is -24% decrease. Please give me brainless if right.
