1.Evaluate<br><br>a.(243/32)^-0.4​
Basile [38]

Answer:

4/9

Step-by-step explanation:

negative exponent means 1/...

so, this is

(32/243)^(4/10) = (32/243)^(2/5)

that means to the power of 2 and then pulling the 5th root.

so, let's pull the 5th root first, and then we square

(32/243)^(2/5) = (2⁵/3⁵)^(2/5) = (2/3)^2 = 4/9

If Logx (1 / 8) = - 3 / 2, then x is equal to<br> A. - 4<br> B. 4<br> C. 1 / 4
Fudgin [204]

Answer:

B. 4

Step-by-step explanation:

Given :

log_x(\frac{1}{8})=-\frac{3}{2}

The logarithm function can be converted to an exponential function as

[\log_ab=c] can be expressed as [a^c=b]

Similarly for the given expression

log_x(\frac{1}{8})=-\frac{3}{2}

We can write,

x^{-\frac{3}{2}}=\frac{1}{8}

Using property of negative exponents [a^{-b}=\frac{1}{a^b}]

\frac{1}{x^{\frac{3}{2}}}=\frac{1}{8}

So we can write that  as:

x^{\frac{3}{2}}=8

Writing the exponents in radical form as a^{\frac{b}{c}}=(\sqrt[c]{a})^b

(\sqrt{x})^3=8

Taking cube root both sides to remove the cube.

\sqrt[3]{(\sqrt{x})^3}=\sqrt[3]{8}

\sqrt x=2

Squaring both sides to remove square root.

(\sqrt x)^2=2^2

∴ x=4

Answer:

Step-by-step explanation:

The coordinate plane is also called a Cartesian Plane. Function. A function is a relationship where there is only one output for every input. In other words, for every value of x, there is only one value for y.
