Given problem: 
.
Solution: We can see that first we have 8 and 2 numbers in front of 10's powers.
So, we need to simplify 8 over 2 first.
If we divide 8 by 2, we get 4.
Now, let us work on 10's and their powers.
is being divided by 
We can apply quotient rule of exponents remaining part.
According to quotient rule of exponents, 
If we apply same rule, we need to subtract exponents of 10's.
If we simplify exponent part -4-(-2), it will give us -4+2 =-2.
So, 
And final answer would be 
.
Answer:
Step-by-step explanation:
<h3>Part A</h3>
- a = 100 will convert the number on the numerator to whole number
- b = 10 will convert the number on the denominator to whole number
But we need a = b in order not to change the value of the fraction, therefore we choose
<h3>Part B</h3>
Multiplying both numerator and denominator by 100 will make the fraction:
- 35.86*100/2.2*100 =
- 3586/220 =
- 16 66/220 =
- 16 3/10
- 16.3
Answer:
1
Step-by-step explanation:
b= -2, b2 +6b +9
=-2(2)+6(-2)+9
=-4-12+9
=4+9-12
=13-12
=1
Answer:
-88 mph
Step-by-step explanation:
We can use the relation ...
time = distance/speed
to compare the times in the two directions.
The wind speed is -88 miles per hour.
_____
The problem statement tells us the travel is slower <em>with</em> the wind than <em>against</em> the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.
