so, rad of x is basically the same thing as x to the 1/2 power. So that's x^ (1/2)
7/x^3 is basically the same thing as 7 TIMES x to the NEGATIVE third power, so 7x^(-3)
So your equation is basically x^(1/2) + 7x^(-3)
From here, you can use power rule.
So your answer would be,
1/2 * x ^(-1/2) - 21*x^(-4)
7/x^3 is basically the same thing as 7 TIMES x to the NEGATIVE third power, so 7x^(-3)
So your equation is basically x^(1/2) + 7x^(-3)
From here, you can use power rule.
So your answer would be,
1/2 * x ^(-1/2) - 21*x^(-4)
