Mathematics

Answer:

The value of f(-4) = -80

Step-by-step explanation:

It is given that,  f(x) = -5x²

<u>To find the value f(-4)</u>

Let  f(x) = -5x²

To find the value of f(-4), substitute -4 instead of x

f(-4) =  -5 * (-4)²

 = -5 * 16      [ since (-4)² = -4 * -4 = 16 ]

 = -80

Therefore the value of f(-4) = -80

Simplify the expression.<br> (the quantity x to the one-sixth power end quantity to the power of 3.)
Usimov [2.4K]

Answer:

\sqrt{x}

Step-by-step explanation:

If we have that worded expression, we can convert it into actual mathematical terms.

x to the one sixth power: x^{\frac{1}{6}}

That to the power of 3:

(x^{\frac{1}{6}})^3

Using exponent rules, since we have a power to a power, the powers multiply, so:

x^{\frac{1}{6}\cdot 3}\\\\x^{\frac{3}{6}}\\\\ x^{\frac{1}{2}}

If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.

So:

x^{\frac{1}{2}} = \sqrt{x}

Hope this helped!

How do I solve this problem
guapka [62]
You first subtract 1/5 from both sides
3/4-1/5 = 11/20 
3/2x=11/20

now you multiply 2/3 on both sides since you have to get x

11/20 * 2/3 
x = 11/30
