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:
Area of the gray region = 64 square units
Step-by-step explanation:
Area of the white square = 64 square units
Length of a side of the given square =
=
= 8 units
By Pythagoras theorem,
Length of diagonal DB =
DB =
=
AD = DB = [Given]
OD = OC =
= 4√2
Therefore, AO = AD + OD = 8√2 + 4√2
= 12√2
Area of ΔACD = Area of ΔAOC - Area of ΔCOD
=
=
=
= 32
Therefore, area of gray part = Area of ΔACD + Area of ΔAED
= 32 + 32
= 64 square units
Answer:
7 1/3
Step-by-step explanation:
Lets do this in steps ok? K!
Important!!!: Look what operation is first in order of operation no parentheses or exponents so division and multiplication is first!
Step 1-- 4 x 7=28
Step 2-- 62 divided by 3 = 20 2/3
Step 3-- 28- 20 2/3
Step 4-- 27 3/3 - 20 2/3= 7 1/3
Hope this helps ∞<3
