Question

Repede va rooooog! Nu mai am timp sa le fac!!!!( Fara a) si b) )

Answer 1

c) x : 10^3 = 10^2

=> x = 10^3 * 10^2 = 10^5

d) 144 : x = 3^2

=> x = 144 : 9 = 4

e) 3^2 + x^2 = 5^2

=> 9 + x^2 = 25

  x^2 = 25-9 = 16

  x = 4

f) 324 : 5^x = (3^2 * 2)^2

=> 324 : 5^x = 18^2

   324 : 5^x = 324

   5^x = 1   =>   x = 0
