Calculati!
a) 10·[1+2¹¹·2¹³+3²⁵÷(3³)⁵+(7²)⁷]÷(7⁰+2⁵¹÷2²⁷+3³·3⁷+(7⁷)²)
b) 4¹⁵÷8⁶+(5¹⁷)³÷125¹⁷+3²×[625÷(5²)²+7¹³×(1024₋2³x2⁷)
Va rog sa ma ajutati!!!

Answer 1

a) 10·[1+2¹¹·2¹³+3²⁵÷(3³)⁵+(7²)⁷]÷(7⁰+2⁵¹÷2²⁷+3³·3⁷+(7⁷)²) =
= 10·(1+2²⁴+3²⁵÷3¹⁵+7¹⁴)÷(1+2²⁴+3¹⁰+7¹⁴) =
= 10·(1+2²⁴+3¹⁰+7¹⁴)÷(1+2²⁴+3¹⁰+7¹⁴) = 10

b) 4¹⁵÷8⁶+(5¹⁷)³÷125¹⁷+3²×[625÷(5²)²+7¹³×(1024₋2³x2⁷)=
=2³⁰÷2¹⁸+5⁵¹÷5⁵¹+3²×[5⁴÷5⁴+7¹³×(2¹⁰₋2¹⁰)=
=2¹²+1+3²×(1+0)=
=2¹²+3²+1=
