What is the cube root of 27a12

satela [25.4K]

Answer:

$3a^4$

Step-by-step explanation:

Given expression is $27a^{12}$ .

Now we need to find the cube root of given expression $27a^{12}$ .

$\sqrt[3]{27a^{12}}$

$=\sqrt[3]{3*3*3a^{4*3}}$

$=\sqrt[3]{3^3\left(a^4\right)^3}$

$=\sqrt[3]{\left(3a^4\right)^3}$

Since cube root and cube are opposite operations of each other. So they will cancel each other.

$=3a^4$

Hence correct choice is the last choice $3a^4$ .

If f(x) = x² + 1 for what x value is f(x) = 2?

MaRussiya [10]

Answer:

x = ±1

Step-by-step explanation:

Step 1: Define variables

f(x) = x² + 1

f(x) = 2

Step 2: Substitute

2 = x² + 1

Step 3: Solve for <em>x</em>

0 = x² - 1

0 = (x - 1)(x + 1)

x - 1 = 0

x = 1

x + 1 = 0

x = -1

∴ x = ±1
