Question 347928
A.
(ab^(2))^(5)

Expand the exponent (5) to the expression.
a^(5)b^(2*5)

Multiply 2 by 5 to get 10.
a^(5)b^(10)

B.(2x)^(2)(2x)^(4)

Expand the exponent (2) to the expression.
2^(2)x^(2)(2x)^(4)

Squaring a number is the same as multiplying the number by itself (2*2).  In this case, 2 squared is 4.
4x^(2)(2x)^(4)

Expand the exponent (4) to the expression.
(4x^(2))*2^(4)x^(4)

Raising a number to the 4th power is the same as multiplying the number by itself 4 times.  In this case, 2 raised to the 4th power is 16.
(4x^(2))*16x^(4)

Multiply 16x^(4) by each term inside the parentheses.
64x^(6)


C.
(m^(3)n^(2))^(3)

Expand the exponent (3) to the expression.
m^(3*3)n^(2*3)

Multiply 3 by 3 to get 9.
m^(9)n^(2*3)

Multiply 2 by 3 to get 6.
m^(9)n^(6)


D.
2^(5)*(2^(-7))/(2^(3))

Raising a number to the 5th power is the same as multiplying the number by itself 5 times.  In this case, 2 raised to the 5th power is 32.
32*(2^(-7))/(2^(3))

To divide 2^(-7) by 2^(3), subtract the denominator exponent from the numerator exponent.
32*2^(-7-3)

Subtract 3 from -7 to get -10.
32*2^(-10)

Remove the negative exponent by rewriting 2^(-10) as (1)/(2^(10)).  A negative exponent follows the rule a^(-n)=(1)/(a^(n)).
32*(1)/(2^(10))

Raising a number to the 10th power is the same as multiplying the number by itself 10 times.  In this case, 2 raised to the 10th power is 1024.
32*(1)/(1024)

Cancel the common factor of 32 from the first term 32 and the denominator of the second term (1)/(1024).
1*(1)/(32)

Multiply 1 by (1)/(32) to get (1)/(32).
(1)/(32)

The approximate value of 2^(5)*(2^(-7))/(2^(3)) is 0.03.
