Describe steps to simplify w(5w^3)^-2 / w^-4

Mathematics
1 answer:
Ulleksa [173]3 years ago
3 0
[w*(5w^3)^-2]/(w^-4)

first rules to consider a^(-b)=1/a^b, (a^b)^c=a^(b*c),   (a^b)*(a^c)=a^(b+c)

[w/(5w^3)^2]/(w^-4) 

(w*w^4)/(25w^6)

w^5/(25w^6)

Then you have the quotient rule for powers (a^c)/(a^b)=a^(c-b)

1/(25w)

which we could state as:

(25w)^(-1) :P

Calculate the original price of these items before the
Aloiza [94]

Answer:

50 and 30.94

Step-by-step explanation:

  • a

The coat cost 46.5 pounds after a 7 percent reduction

so we can write:

  • 46.5⇒ (100-7)⇒ 93 percent
  • x(the initial price) ⇒ 100 percent

using the proprtionality relation:

x= (100*46.5)/93 = 50

so the initial price of the coat is 50 pounds

  • b

The jumper costs 32.8 pounds after an increase of 6 percent

so:

  • 32.8⇒(100+6)⇒ 106 percent
  • x (the initial price)⇒ 100 percent

using proportionality:

x= (100*32.8)/106 = 30.94

the initial price is 30.94 pounds

Step-by-step explanation:

Consider ΔKLJ:

sinθ=opposite/hypotenuse

sin30=LJ/8√2

LJ=0.5*8√2=4√2

Consider ΔMLJ:

sinθ=opp/hyp

sin45=x/4√2

1/√2=x/4√2

4√2/√2=x

x=4
