THIS IS URGENT I NEED HELP ASAP.(9x 10^-3)^2

simplify. write in scientific notation
a 8.1x10^-5
b 81x10^-4
c 81x10^-3
d 8.1x10^-6
Evaluate 1/2a^-4b^2 for a =-2 and b=4
a2
b 1/2
c3
d4
is the following statement always, never, or sometimes true?
a number raised to a negative exponent is negative?
A always
B never
C sometimes

(9x 10^-3)^2=, so d 8.1x10^-6

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

A number raised to a negative exponent is sometimes negative.

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

step-by-step explanation:

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

when the constitution was formally published 2 years later (1857). it also contained an article which permitted education free from any religious influence, the removal of the catholic church institutional privileges, and the sale of property belonging to the church. all of these provisions were clearly against the catholic church interests.
