(2¹⁷×3¹⁵):6¹⁴

=(2x3)¹⁵:6¹⁴x2²=6¹⁵:6¹⁴x2²=6x2²=6x4=24

(4⁷×9¹⁰)²:(2²⁵×27¹³)=(2¹⁴x3²⁰)²;(2²⁵x3³⁹)=(2²⁸x3⁴⁰):(2²⁵x3³⁹)=2³x3=8x3=24

12⁷:(2¹⁰×3⁵) =((2²)⁷x3⁷):(2¹⁰x3⁵)=(2¹⁴x3⁷):(2¹⁰x3⁵)=2⁴x3²=16x9=144

[2¹⁷×2⁴³+(3¹⁵)³+5²⁸]:(4³⁰+5¹⁷×5²³+3⁷²:3²⁷)​=

1+ [tex]3^{45-45}[/tex]  + [tex]5^{28-40}[/tex]= 1+ 1+ [tex]5^{- 12}[/tex]      cred ca e o greseala pt ca si in cazul lui 5 trebuia sa dea 1 si rezultatul final era (1+1+1)= 3
