Answer 2

Oblicz:

a)   7do potegi12 *3+4*7 do potegi12

---------------------------------------------------  =......?

(7 do potegi12 : 7do potegi 8) do potegi3

 

 

    7¹² *3 + 4*7¹²

=  ----------------- =

   ( 7¹² : 7⁸)³

 

    7¹²*( 3 +4)

= ---------------  =

   (  7⁴)³

 

    7¹²*7

= --------- = 

    7 ¹²

 

     7¹³

=  ------ =  7¹³⁻¹² = 7¹ = 7

     7¹²

 

 

b) 8*3do potegi4*3 do potegi11 - 9*3do potegi12

---------------------------------------------------------=......?

46*(3do potegi18 : 3do potegi4)

 

    8*3⁴*3¹¹ -3²*3¹²

= ----------------------- =

 46*(3¹⁸ : 3⁴)

 

    8*3¹⁵ - 3¹⁴

= ---------------=

   46* 3¹⁴

 

   8*3* 3¹⁴- 1*3¹⁴

= -------------------- =

     46*3¹⁴

 

    3¹⁴*(8*3 -1)

= ---------------- =

    46*3¹⁴

 

   3¹⁴*23

= ---------- =

    3¹⁴*46

 

    23

= ----- =   ½

   46
