Exercise 1 Page 480

To simplify the given expression, remember that the numerator of a rational exponent is the exponent of the expression, and the denominator is the index. a^()1 n=sqrt(a) Let's simplify the expression!

(27x^2)^(13)

PowProd

(a * b)^m=a^m* b^m

27^(13)* (x^2)^(13)

PowToRootD

a^(1n)=sqrt(a)

27^(13)* sqrt(x^2)

CalcPow

Calculate power

3* sqrt(x^2)

Multiply

Multiply

3sqrt(x^2)

Finally, we can say that the correct answer is B.
