How do I go about solving (27x^3/8y^9)^5/3? And what is the role of the numerator and denominator?

MrRissso [65]

$\left( \frac{27x^3}{8y^9}\right)^ \frac{5}{3} \\\\\\ =\left( \frac{(3x)^3}{(2y^3)^3}\right)^ \frac{5}{3} \\\\\\ = \frac{(3x)^{3 \times \frac{5}{3} }}{(2y^3)^{3 \times \frac{5}{3} }} \\\\\\ =\frac{(3x)^5}{(2y^3)^{5 }} \\\\\\ =\frac{243x^5}{32y^{15}}$

Now, If the exponent was negative like you asked....

$\left( \frac{27x^3}{8y^9}\right)^ {-\frac{5}{3}} \\\\\\ =\left( \frac{8y^9}{27x^3}\right)^ {\frac{5}{3}}\\\\\\ =\left( \frac{(2y^3)^3}{(3x)^3}\right)^ \frac{5}{3} \\\\\\ = \frac{(2y^3)^{3 \times \frac{5}{3} }}{(3x)^{3 \times \frac{5}{3} }} \\\\\\ =\frac{(2y^3)^{5 }}{(3x)^5} \\\\\\ =\frac{32y^{15}}{243x^5}$

ASHA 777 [7]

Answer:

see the attached graph

Step-by-step explanation:

When an equation is in standard form (or almost standard form), I like to put it into intercept form for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).

x +3y = -3

Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:

x/(-3) +y/(-1) = 1

The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.

Answer:

The answer is D. 3

Step-by-step explanation:

A number refers to the expression of a quantity or a magnitude. In mathematics, a number represents a fixed quantity of something or generally of a number system.

The numbers have a fixed order that determines their value.

The numbers are in order of:

Unit = 8

Ten = 3

Hundred = 5

Unit of thousand = 7

Ten thousand = 2

Hundred thousand = 4

Million unit = 1

10 million = 4

And a hundred million represented by = 3.
