Sure. Here's an example.

$\sqrt{\dfrac{49}{81}}=\dfrac{7}{9}$

Another one might look like this. $\sqrt[4]{16} = 2$

And just one more

$\sqrt[3]{8000} = 20$

Answer:

Step-by-step explanation:

AB is a tangent to circle o

ABO is a right-angled

AO²=AB²+BO²

$BO=\sqrt{AO^{2}-(AB)^{2})\\}\\\\\sqrt{(8.6)^{2}-(5)^{2} } \\\\=\sqrt{73.96-25} \\\\=\sqrt{48.9} \\\\=6.99\\\\Answer=7$

hope it helps....

Which expression is equivalent to (2^5)^-2

irinina [24]

<u><em>1/1024 is the correct answer.</em></u> First you had to apply exponent rule, and it gave us, $\frac{1}{(2^5)^2}$ , or $2^5^*^2$ . Then you can also refine, and it gave us, $2^10$ , or $\frac{1}{2^10}$ . And it gave us the answer is $2^1^0=2*2*2*2*2*2*2*2*2*2=1024$ , or 1/1024 is the correct answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
