Explanation:

I am guessing you´re simplifying this equation.

(The 4 is still an exponent)

Rewrite
√(-3) as
√(-1(3))

Now rewrite the equation before as
(√(-1) *√(3) )^(4)

Now rewrite
√(-1) as
i


(i*√(3) )^(4)

You will then apply the product rule to
i√(3)


i^(4) √(3) ^(4)

Now rewrite
i^(4) as 1

You first have to rewrite


i^(4) as (i^(2) )^(2) .


(i^(2) )^(2) √(3) ^(4)

Now
i^(2) as -1


(-1)^(2) √(3) ^(4)

Then raise -1 to the second power


1√(3) ^(4)

Now multiply
√(3) ^(4) by
1


√(3) ^(4)

Now here comes the longest part

Rewrite
√(3) ^(4) as
3^(2)

You first have to use
\sqrt[n]{a^(x) } = a^{(x)/(n) } to rewrite
√(3) as
3^{(1)/(2) }


(3^{(1)/(2) } )^(4)

Apply the power rule and multiply the exponents ,
(a^(m) )^(n) = a^(mn)


3^{(1)/(2) } *4

Now combine
(1)/(2) and
4


3^{(4)/(2) }

Now you have cancel the common factor of 4 and 2

Factor 2 out of 4


3^{(2*2)/(2) }

Cancel the common factors

Now factor 2 out of 2


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

Cancel the common factor


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

Rewrite the expression


3^{(2)/(1) }

Divide 2 by 1


3^(2)

Raise 3 to the second power´
