You can tell right away 5/6 isnt the smallest then 1/3 is smaller than 3/7 so that leaves 2 answers since 1/3 of 14 is 4 . 666666 so 1/3 is the smallest

To find which one is the smallest, we must first give the fractions a common denominator. That number happens to be 42. Rewriting the fractions results in:

<span>3/7 becomes 18/42
1/3 becomes 14/42
5/6 becomes 35/42
9/14 becomes 27/42
</span>
When placed in this format, we can see that 1/3 is in fact the smallest. Hope this helps :)

What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4

Ivahew [28]

For the exponential expression, $16^{1/4}$ the simplified value is 2.

<h3>How to simplify the exponential expression?</h3>

First, we need to remember a rule for exponential expressions, it says that:

$x^{1/n} = \sqrt[n]{x}$

Then we can rewrite the given exponential expression as:

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

So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.

We know that:

2*2 = 4

Then:

2*2*2*2 = 2⁴ = 4*4 = 16

Then we can conclude that:

$16^{1/4} =\sqrt[4]{16} = 2$

So the simplified value of the exponential expression is 2.

Solve the system by substitution. (Please Explain how you did it Ill give brainliest)

Musya8 [376]

Because the last equation already has the y eliminated so just need to get the other two to eliminate the y too

multiply 4 to the first equation to eliminate y, and you get
-4x-4y-4z=-32
-4x+4y+5z=7
now get rid of y so all you have left is
-8x+z=-25 (let call this equation #4)

now take equation #3 and #4 together to solve for one of the variables, i’ll solve for z first so i’ll get rid of x by multiply the equation #4 all by 4, you get

8x+8z=16
-8x+z=-25
solve it and get 9z= -9; z=-1

now you have z so take it and ply it into equation #3
2x+2(-1)=4
2x=6; x=3

take both of them, plug it in equation #1
-3-y-(-1)=-8
-y=-6 ; y=6

done so the answer is (x,y,z) = (3,6,-1)
