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 $3a^4$ .

Someone please help me w this standard form question

svp [43]

Answer:

2.4 × 10⁶

Step-by-step explanation:

Given:

$\sf x=3.8 \times 10^5$

$\sf y=5.9 \times 10^4$

To calculate the value of R, substitute the given values into the given formula:

$\begin{aligned}\sf R & = \sf \dfrac{x^2}{y}\\\\ \implies \sf R& = \sf \dfrac{(3.8 \times 10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{3.8^2 \times (10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44 \times 10^{10}}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44}{5.9} \times \dfrac{10^{10}}{10^4}\\\\& = \sf 2.4474... \times 10^{(10-4)}\\\\& = \sf 2.4474... \times 10^6\\\\\end{aligned}$
