Answer:
a = 1/64
Step-by-step explanation:
3 + 4 a ^ 1/6 = 5
1. move constant to the right side and change its sign
4 a ^ 1/6 = 5 - 3
2. using <em>a</em><em> </em><em>^</em><em> </em><em>m/</em><em>n</em><em> </em><em>=</em><em> </em><em>n√a^m</em><em> </em><em> </em>transform the expression
4 6√a = 5 - 3
3. Subtract the numbers
4 6√a = 2
4. Divide both sides of the equation by 4
6√a = 1/2
5. Raise both sides of the equation to the power of 6.
a = 1/64

Answer:
Here we will use the relationships:



And a number:

is between 0 and 1 if a is positive and larger than 1, and n is negative.
if a is positive and 0 < a < 1, then we need to have n positive such that:
0 < a^n < 1
A) 
This is between zero and 1,
B) 
This is greater than 1, because the exponent is positive.
C) 
Because a is smaller than 1, and the exponent is positive, then the expression is between 0 and 1.
D) 
The exponent is negative (and pair) then the expression is between 0 and 1.
Remember that when the exponent is pair, we always have that:
(-N)^m = (N)^m
So (-7)^-2 = 7^-2
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.
