yes i wrote the problem correctly
it tells you to use rational exponents to write the problem i gave as a radical expression and then choose from the following four answers

Question

anonymous · Answer

thats if i am understanding this problem correctly

anonymous · Answer

that is not one of the choices the others are:$$\sqrt[4]{175616}$$$$\sqrt[8]{56}$$$$\sqrt[4]{392}$$$$1/\sqrt{392^{4}}$$

anonymous · Answer

you can add the exponents unless the bases are the same.

anonymous · Answer

cant*

anonymous · Answer

since 7 and 8 are different you cant add them like that.

anonymous · Answer

$$8^\frac{1}{4}*7^\frac{1}{2} = 8^\frac{1}{4}*7^\frac{2}{4} = 8^\frac{1}{4}*49^\frac{1}{4} = (8*49)^\frac{1}{4} =  392^\frac{1}{4}$$

joemath314159 the correct ans. is:
1/392^4

anonymous · Answer

where is the original problem? i was going off what someone posted.

anonymous · Answer

Use rational exponent to write $$\sqrt[4]{8} * \sqrt[2]{7}$$ as a radical expression and choose from the following answers I posted ahead and above

joe i just did that lol on his previous post

myininaya · Answer

lol u won :(

anonymous · Answer

i dont feel like i won lol >.>
theres nothing wrong with my answer.

myininaya · Answer

speed racer

anonymous · Answer

$$392^\frac{1}{4} = \sqrt[4]{392}$$

myininaya · Answer

yours say 6 min ago my said 2 min ago
so i lost

anonymous · Answer

so guys what the finaal ans.

anonymous · Answer

you still get a medal!

myininaya · Answer
