Answer 1

Explicație pas cu pas:

11.a)4³-3³÷(2⁶-2⁵-2⁴-2³-2²-2²-2¹-2⁰)=

=64-27÷(64-32-16-8-4-2-1)=

=37÷(32-31)=

=37÷1=

=36

b)(7⁴+7³+7²)÷7²+8⁴÷4⁴=

=7²(7²+7+1)÷49+(2³)⁴÷(2²)⁴=

=49(49+8)÷49+2¹²÷2⁸=

=49×57÷49+2⁴=

=2793÷49+16=

=57+16=

=73

c)(5³÷5+2²×3)-(2²+1²⁰¹⁴+6)=

=(5²+4×3)-(4+1+6)=

=(25+12)-(5+6)=

=37-11=

=25

d)[(2⁴)²÷2⁴×2²⁰¹⁴÷2⁹]×3-48×2²⁰⁰¹=

=(2⁸÷2⁴×2²⁰¹⁴÷2⁹)×3-3×2⁴×2²⁰⁰¹=

=2⁸-⁴+²⁰¹⁴-⁹×3-3×2²⁰⁰⁵=

=2²⁰⁰⁹×3-3×2²⁰⁰⁵=

=3×2²⁰⁰⁵×(2⁴-1)=

=3×2²⁰⁰⁵×(16-1)=

=3×2²⁰⁰⁵×15=

=45×2²⁰⁰⁵
