Plz help me with the following problems.

Simplify. 5^-1(3^-2)

Simplify. mn^-4/p^0q^-2

Write a scientific notation. 0.0042

Write in standard notation. 6.12*10^3

Simplify. Write in scientific notation. 0.5(8 * 10^5)

Simplify. Write in scientific notation. (9 * 10^-3)^2

Evaluate 1/2a^-4b^2 for a=-2 and b=4.

Simplify (4xy^2)^3(xy)^5

Simplify (2t^-3)^3(0.4r)^2

Actually I only need help with the second problem,and the 7th problem,

Simplify. mn^-4/p^0q^-2

Evaluate 1/2a^-4b^2 for a=-2 and b=4.
p^0 = 1, so

mn^-4/p^0q^-2 = (m/n^4) / (1/q^2) = mq^2/n^4

1/(2 (-2)^-4 (4)^2)
1/(2 (1/16) (16))
1/2

Note that (-2)^4 = (-2)(-2)(-2)(-2) = +16
Thank you Steve~!
