Question

Can you please explain this one to me?
It looks very easy but I'm just not catching on...

Answer 1

That appears to be the square root and the cube root...so what you really have is:

(2^(1/2))*(2^(1/3))

Now the rule for multiplication of similar bases with different exponents is:

a^b*a^c=a^(b+c), so in this case:

2^(1/2)*2^(1/3) is equal to

2^(1/2+1/3) which is equal to

2^(5/6)
