Question

1:Efectuați
a) 10•(3⁴-576:12) =
b) (7¹³:7¹¹-7⁰):2⁴ =
c) (225:5²+5⁰)³:10²=​

Answer 1

a) 10•(3⁴-576:12)=

= 10•(81-48)=

=10•33=

=330

b) (7¹³:7¹¹-7⁰):2⁴=

=(7²-1):16=

=(49-1):16=

=48:16=

=3

c) (225:5²+5⁰)³:10²=

=(225:25+1)³:100=

=(9+1)³:100=

=10³:100=

=1000:100=

=10

Answer 2

Răspuns:

a= 330 b= 3 c= 10000

Explicație pas cu pas:

A . 10 * ( 81- 576:12 ) = 10* ( 81-48)= 10*33=330

B . (7*13(laputere) :7*11(la putere) -7*0( la putere) ):2*4=(96889010507:1977326743-1):16=(49-1):16=48:16=3 C . (255:25+1)3:100=(9+1)3:100=10*3(la putere):100=1000000:100=10000
