What is the simplified value of the exponential expression 16^1/4?

The simplified value of the exponential expression 16^(1)/(4)is 2.

What does Fractional power mean for an integer?

Fractional power implies the root of the strength of the denominator of that integer.

For example: a^(1)/(n)=\sqrt[n]{a}.

Given here the exponential expression is 16^(1)/(4)

So here a=16,n=4

We know that, 2^4=16

Thus, 16^(1)/(4)=\sqrt[4]{16}=\sqrt[4]{2^4}=2

Hence the equivalent value of the given expression 16^(1)/(4) is 2.

Answer

2

Explanation

First, we are going to use the law of fractional exponents: a^{(1)/(n) =\sqrt[n]{a}

We can infer form our expression that a=16 and n=4, so let's replace the values:

a^{(1)/(n) =\sqrt[n]{a}

16^{(1)/(4) }=\sqrt[4]{16}

Notice that we can also decompose 16 into prime factors to get 16=2^4, so we can rewrite our expression as follows:

\sqrt[4]{16}=\sqrt[4]{2^4}

Finally, we can use the rule of radicals: \sqrt[n]{a^n} =a, so:

\sqrt[4]{2^4}=2

I can't figure this outthis question was on my exam and I got it completely wrong
(I have a graphing calculator capble of matrices so yo don't have to solve the system of equations by hand, use rref (reduced row echelon form))


values of a, b, and c and the equation of the graph of the parabola
y=ax^2+bx+c
such that is passes through the points
(2,-15)
(-5,-29)
(-3,5)

rewrite it in the form (x-h)^2=4P(y-k)

show all work
if I were to sub the points in I would ge
(2,-15): -15=4a+2b+c
(-5,-29): -29=25a-5b+c
(-3,5): 5=9a-3b+c

then solve for a, b and c
I don't know how to solve, please help
(if I don't undestand your answer, I will either report or ask you to explain more)

Suppose that equation of parabola is
y =ax² + bx + c


Since parabola passes through the point (2,−15) then 
−15 = 4a + 2b + c

Since parabola passes through the point (-5,-29), then
−29 = 25a − 5b + c

Since parabola passes through the point (−3,−5), then 
−5 = 9a − 3b + c


Thus, we obtained following system:
4a + 2b + c = −15
25a − 5b + c = −29
9a − 3b + c = −5

Solving it we get that 
a = −2, b = −4, c = 1

Thus, equation of parabola is
y = −2x²− 4x + 1

____________________

Rewriting in the form of 
(x - h)² = 4p(y - k)

i) -2x² - 4x + 1 = y

ii) -3x² - 7x = y - 11
(-3x² and -7x are isolated)

iii) -3x² - 7x - 49/36 = y - 1 - 49/36
(Adding -49/36 to both sides to get perfect square on LHS)

iv) -3(x² + 7/3x + 49/36) = y - 3
(Taking out -3 common from LHS)

v) -3(x + 7/6)² = y - 445/36 

vi) (x + 7/6)² = -⅓(y - 445/36) 
(Shifting -⅓ to RHS)

vii) (x + 1)² = 4(-1/12)(y - 445/36)
(Rewriting in the form of 4(-1/12) ; This is 4p) 


So, after rewriting the equation would be - 

(x + 7/6)² = 4(-⅛)(y - 445/36)

If p and a vary inversely and p is 26 when q is 5, determine q when p is equal to 10

Answers

Answer: q = 13

because p and q are inverse

=>  26/10 = q/5

⇔ q = 26/10.5

⇔ q = 13

The vertices of a feasible region are (14, 2), (0, 9), (6, 8), and (10, 3). What is the maximum value of P if P = 180x + 250y?

Answers

For this problem, we must first plot of each point using the given points. Assume that each coordinate given is in the (x,y) form. To get the maximum value, we can plus in each coordinate set to the equation to see which P comes out to be the largest. For (14,2), P=3020. For (0,9), P=2250. For (6,8), P=3080. For (10,3), P=2550. The maximum value for P would be P=3080.
