Explanation:
what do you mean by "solve this" ?
only an equation can be solved.
for that your expression would need to be equal to something. like = 0 or anything else.
in this case we can only simplify.
remember,
x^a × x^b = x^(a+b)
it is exactly the same here
x^6 × x^(4/3) = x^(6 + 4/3)
the only thing we can do now is to convert the mixed fraction
6 4/3
into a full fraction.
for that we have to ask how many 1/3 are in 6 ?
there are 3 in 1, so there are 3×6 in 6.
therefore,
6 4/3 = (3×6 + 4)/3 = (18 + 4)/3 = 22/3.
so, our final answer is
x^(22/3)
