Question 2
When evaluating the expression x^4 x x^4 x x^4 x x^4 it would be written as x^4+4+4+4, adding the exponents instead of multiplying them.
Question 3
x(15)\sqrt(x^(13))
Question 4
(5)\sqrt(x^4)/(10)\sqrt(x^7)
Question 5
1/(1/(27)\sqrt(x^3)
You can convert to radical form using the formula a^x/n = (n)\sqrt(a^x)
