Answer:

x=-7

Step-by-step explanation:

first, subtract 4x from both sides. then you'll get:

-9=3x+12

next subtract 12 from both sides. Then you'll get:

-21=3x

then you divide each side by 3. You get:

x=-7

Find the equivalent exponential expression. [(-4)^5]^3

Sunny_sXe [5.5K]

Answer:

$-4^{15}$

Step-by-step explanation:

Given expression:

$\left[(-4)^5\right]^3$

$\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:$

$\implies (-4)^{(5 \times 3)}$

$\implies (-4)^{15}$

$\textsf{Apply exponent rule} \quad (-a)^n=-a^n,\:\: \textsf{ if }n \textsf{ is odd}:$

$\implies -4^{15}$

Are there concepts/processes to strictly follow in writing radicals as expressions with rational exponents?

Eva8 [605]

Answer:

The concept or process is $x^{\frac{m}{n}}=(\sqrt[n]{x})^m$ .

Step-by-step explanation:

Consider the provided information.

The following property can be used to rewrite each radical as an exponent.

The numerator tells the power of the resulting rational exponent, and the denominator of the rational exponents tells the root of that number.

$x^{\frac{m}{n}}=(\sqrt[n]{x})^m$

For example:

$(27)^{\frac{2}{3}}=(\sqrt[3]{27})^2$

$(27)^{\frac{2}{3}}=(3)^2$

$(27)^{\frac{2}{3}}=9$

Hence, the concept or process is $x^{\frac{m}{n}}=(\sqrt[n]{x})^m$ .
