Question

calculati a ) [9²+9•(5²-3•2³+7)]"3²+1²⁰²¹ b) [2⁰+2¹+3¹⁵:(3•3¹³)]²:3²-0²¹²¹ VA ROG HELP DAU COROANA LA PRIMU
​

Answer 1

Explicație pas cu pas:

a ) [9²+9•(5²-3•2³+7)]:3²+1²⁰²¹=[9²+9•(25-3*8+7)]:3²+1²⁰²¹=

[9²+3²•(25-24+7)]:3²+1²⁰²¹= (9²+3²•8):3²+1=

=3²(3²+8):3²+1=9+8+1=18

b) [2⁰+2¹+3¹⁵:(3•3¹³)]²:3²-0²¹²¹= (1+2+3¹⁵:3^14)^2:9=

(1+2+3)^3:9= 6^3:9=36*6:9=4*6=24
