If anybody could kindly help me figure this all out it would be greatly appreciated. Some i've attempted and need to know if its right, and some I have no clue how to approach.
Simplify, express each answer with positive exponent if possible.
-45 x^5 y^7 z^9 / 9 x^7 y^7 z^5
i got = -5 x^-2 z^4
next question.
(x ^a+b) ^a-b / (x ^a-2b) ^a+2b
next question.
find the equation for y
x-axis as asymptote
passes through points 0,-1 -1,-3 -2,-9
Next question.
Log5 20 +log5 10 - 3 log5 2
=log5 200 - 3 log5 2
=?
Next question. evaluate each of the following
7 ^(log7 12)
log1/3 1
log3 81"square root symbol" 27 under it.
last question.
an earthquake registers 6.1 on the richter scale. what is the rating on an earthquake that is twice as powerful?
