Topic: **Fractions math homework help****Question:**
I'm having some trouble with a few problems in math. COuld you help me pls?
Keys:
=x= Exponent, so a=3= would mean a by the power of 3
------ means a line of fraction. So 9
---- equals 9/5
5
7ab=-2=
------------
3w
7s
---------
5t=-3=
7s=0= t =-5=
----------------------
2 =-1= m =2=
Evaluate each expression for r=-3 and s=5
s =0=
---------
r =-2=
2 =-4= r =3= s =-2=
Thank you in advance!
Oh, the first few were simplify

The negative exponent moves the term to the opposite place in a fraction with a positive exponent. And anything to the 0 power (except 0) equals 1. I'm not sure what the directions are for the first ones, maybe "Write with no negative exponents"? then 7a ----- 3b²w like that On the last one, s⁰ = 1 and the r goes up top as r² which is (-3)² = 9 so 9 and the other one after moving the terms with negative exponents is r³ ---- 2⁴ s² -27 ----- 400

good question. you just take 1.015^4 and switch it to the top. for example, if you have 1 --- 2*2^-3 you just switch anything with a negative exponent to the top 1*(2^3) ----------- 2 and your final answer is eight over two, which simplifies to four

(a million/32)^(-3/5) = ((a million/32)^(a million/5))^(-3) = (a million/2)^(-3) = 2^3 = 8 sixteen ^(-3/4) = (sixteen)^(a million/4)^(-3) = 2^(-3) = (a million/2)^3 = a million/8 2 key issues right here: taking a detrimental fraction exponent is comparable to taking the reciprocal first, and then elevating to the advantageous fractional exponent. Fractional exponents is comparable to taking a root (so 32^(a million/5) = 2) because of the fact 2 is the 5th root of 32.

examine out this trend: 10^4 = 10,000 10^3 = one million,000 10^2 = a hundred 10^one million = 10 what's next in this trend? nicely the exponent is going down one million each and every time so that's going to start up 10^0. And the solutions get divided via 10 each and every time so 10 ÷ 10 = one million 10^0 = one million this could ensue no remember what extensive variety you utilize because of the fact the backside, different than for 0. Then examine out this question: Simplify y^3 ----- y^5 the guideline is subtract the exponents, proper? So that's y ^ (3 - 5) = y ^ -2 yet whilst instead you write them out and cancel, y•y•y ------------- y•y•y•y•y you finally end up with one million over y^2 so this shows that detrimental exponents basically propose reciprocals.

1). (x^b)^a = x^(ba) [x^b][x^a] = x^[b+a] [x^b]/[x^a] = x^[b-a] 2). a). If b is greater than 1 then the graph will be going upward as x increases at a non constant rate like e^x b). If b = 1 than the graph will be completely horizontal at y = a c). If b is between 0 and 1 then the graph will be going down as x increases at a non constant rate like (1/2)^x 3). a is greater than 1 then the graph will be going upward as x increases at a non constant rate like e^x b). If a = 1 than the graph will be completely horizontal at y = a c). If a is between 0 and 1 then the graph will be going down as x increases at a non constant rate like (1/2)^x

i'm going to attempt to teach you the thank you to do them. whilst dividing words concerning exponents then the exponent in the denominator is subtracted from the exponent in the numerator (like words in simple terms of direction) a) right here we in simple terms have words in w and following the guideline we get a single exponent via subtraction viz -2 - ( - 3) = -2 + 3 = a million ie w^a million or in simple terms w is the respond b) -a million -( +4) = -5 ie p^-5 they're each and all of the comparable you in simple terms would desire to be careful with the indicators. c) this time there are 2 distinctive style of words so do separately q^2m^8 divided via q^-1m^6 for q words we get new exponent = 2 - (-a million) = 2 + a million = 3 for m words exponent = 8 - ( 6) = 2 giving q^3m^2 they're each and all of the comparable and in case you have been multiplying you're able to upload the exponents. i'm going to enable you stumble on the numerical values
