anonymous · Answer

Either A or C

anonymous · Answer

Is the problem:$$a ^{(5/7)}$$

anonymous · Answer

Or$$\frac{ a ^{5} }{ 7 }$$

anonymous · Answer

Hint:  answer C is not in radical form...

anonymous · Answer

Yes

I'm not sure how to go about this

anonymous · Answer

The numerator of the exponent is just like a normal exponent...  but the denominator means you could rewrite it as "the seventh root of (a to the fifth power)"

anonymous · Answer

It looks like answer B....   assuming that 7 in front actually means "7th root" and not "7 multiplied by"

Same confusion for me as on that other one...

I said that in my other question posted....I was right! :)

My apologies, but it made sense to me. I'll be clearer.....!
