Explanation:
Before we start, let's revise the exponent rules,
- Product rule:
a^x xxa^y=a^(x+y - Quotient rule:
a^x -:a^y=a^(x-y - Power rule:
(a^x)^y=a^(xy) - Power of a product rule:
(ab)^x=a^x xx b^x - Power of a quotient rule:
(a/b)^x=(a^x)/(b^x) - Zero exponent:
a^0=1 - Negative exponent:
a^-x=1/a^x - Fractional exponent:
a^(x/y)=root(y)(a^x)
Now let's begin,
Using rule 8 - Fractional exponent, we get,
