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 $3a^4$ .

Pls help and show workings.... due ASAP <br> SHOW WORKINGS PLEASE!

MrRa [10]

Answer: 7.29 or 7 1/4 or 29/4 (they're all equal, just rewritten)

Step-by-step explanation:

the angles are equal, so we set the equations to each other and then solve. here's my work:

12k - 9 = 8k + 20

12k (- 8k) - 9 = 8k ( - 8k) + 20

4k - 9 = 20

4k -9 ( + 9) = 20 ( + 9)

4k = 29

k = 7.29 or 7 1/4 or 29/4
