• This Question is Open
1. NeedsGoodAnswer

anything with a ^2 after it is supposed to be squared

2. myininaya

Is that: $\frac{8^2}{\sqrt{16+5^2-8}}$

3. NeedsGoodAnswer

$8\div \sqrt{16}+5^{2}-8$

4. myininaya

$\frac{8}{\sqrt{16}}+5^2-8$

5. NeedsGoodAnswer

so its $1+5^{2}-8$?

6. myininaya

$\sqrt{16}=4$

7. NeedsGoodAnswer

or actually its $2+5^{2}-8?$

8. myininaya

Yes

9. NeedsGoodAnswer

then you simplify the 5 squared to $2+25-8$

10. myininaya

yes!

11. NeedsGoodAnswer

so 2+25 = 27 27-8 = 19?

12. myininaya

yes!

13. NeedsGoodAnswer

then what because 19 is not an answer and im lost after that.......

14. myininaya

$\frac{8}{\sqrt{16}}+5^2-8=\frac{8}{4}+5^2-8=2+25-8=27-8=19$ Yep it is the answer! Be sure that the problem I have looks exactly like the problem you have.
