Which expression is equivalent to Negative 32 Superscript three-fifths?

Sidana [21]

Answer:

$-8$

Step-by-step explanation:

Given: $(-32)^{(\frac{3}{5}) }$

To choose: the correct option

Solution:

Power refers to a number of times, a number is multiplied by itself. Another name for power is exponent.

As per rule of exponents, $(a^m)^n=a^{mn}$

Here,

$(-32)=(-2)^5$

Therefore,

$(-32)^{(\frac{3}{5}) }=[(-2)^5]^{(\frac{3}{5}) }=(-2)^{5(\frac{3}{5}) }$

Here, $a=-2,m=5,n=\frac{3}{5}$

So,

$(-32)^{(\frac{3}{5}) }=[(-2)^5]^{(\frac{3}{5}) }=(-2)^{5(\frac{3}{5}) }=(-2)^3=-8$

do you agree that not all quadratic equations can be solved by factoring? justify your answer by giving examples.

Talja [164]

In some cases, there are better solutions than factoring. Consider, for example the quadratic equation x^2+x+1, which is much easier to solve using the quadratic formula than by factoring.

A cylinderical container of height 28cm and diameter 18cm is filled with water. The water is then poured into another container

tiny-mole [99]

Answer:

h = 24 cm

Step-by-step explanation:

volume of water in the cylinder = volume of water in the rectangular base container

But ,

volume of cylinder = $\pi$ $r^{2}$ h

where: is the radius and h is the height.

volume of cuboid = length x width x height

= l x w x h

So that;

$\pi$ $r^{2}$ h = l x w x h

But, r = $\frac{diameter}{2}$ = $\frac{18}{2}$ = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, $\pi$ = $\frac{22}{7}$ .

Thus,

$\frac{22}{7}$ x $(9)^{2}$ x 28 = 27 x 11 x h

$\frac{22}{7}$ x 81 x 28 = 27 x 11 x h

7128 = 297h

h = $\frac{7128}{297}$

= 24

h = 24 cm

The depth of the water in the container is 24 cm.
