Which is equivalent to 16 3/4x ?

The answer

the question is not very clear,
its complement may be Which is equivalent to 16 ^ 3/4x?

-4√16^3x
-4√16^3
-3√16^4x
-3√16^4

perhaps the 16 3/4x should be written as [16 ^ 3] / 4x, or 16 ^ (3 / 4x)
or - [16 ^ (3 / 4)] x

If the question is [16 ^ 3] / 4x, then none of the choices is equivalent to this
if the question is 16 ^ (3 / 4x), it is equivalent to 4x-th root of 16^3

so if the question is - [16 ^ (3 / 4)] x
so - [16 ^ (3 / 4)] x =( - 4√16^3)x it is 4th root of 16^3 times x

so the choice is -4√16^3x

Answer:

$\sqrt[4]{16^{3x}}$

Step-by-step explanation:

we have

$16^{\frac{3}{4}x}$

we know that

$16^{\frac{3}{4}x}=(16^{3x})^{\frac{1}{4}}=\sqrt[4]{16^{3x}}$

therefore

$16^{\frac{3}{4}x}=\sqrt[4]{16^{3x}}$

Solve: (x ÷ 4) + 8 = 38

Rainbow [258]

First you have to rewrite the equation:
(x ÷ 4) + 8 = 38

Second you have to write the division as fraction:
(¼x) + 8 = 38

Third you have to take off the unecessary bracket:

¼x + 8 = 38

Fourth multiply 8 and 38 by 4
x + 32 = 152

Fifth step move the constant to the right hand and change the sign.
x = 152 - 32

Then subtract:

x = 120

Hope this helps :))

Solve 3x2 = −12x − 15. x = −4 ± 2i x = −4 ± i x = −2 ± 2i x = −2 ± i

diamong [38]

ANSWER

$x = - 2 \pm i$

EXPLANATION

We use the method of completing the squares.

The equation is
$3 {x}^{2} = - 12x - 15$

We rewrite the above equation to obtain;

$3 {x}^{2} + 12x = - 15$

We divide through by 3 to obtain;

${x}^{2} + 4x = - 5$

We add half the coefficient of
$x$

to both sides of the equation to get,

${x}^{2} + 4x + {2}^{2} = - 5 + {2}^{2}$

The right hand side is now a perfect square.

${(x + 2)}^{2} = - 1$

We now take square root of both sides to get;

$x + 2 = \pm \sqrt{ - 1}$

We add -2 to both sides,

$x = - 2 \pm \sqrt{ - 1}$

We simplify to obtain,

$x = - 2 \pm i$
