Question

Dau 61 de puncte, va rog!!!!

Answer 1

2)
a)=4²-3²=16-9=7
b)=3²⁵:3²³=3²=9
c)=3²⁴:3²⁴=1
d)=4³-4³=0
e)=5¹⁷⁶⁺⁰⁺²⁴⁻¹⁹⁹=5⁰=1
f)=6²⁴-6²⁴=0
g)=5⁶(5¹+5²+5³):5⁶=(5¹+5²+5³)=5+25+125=155
h)=7⁴(1+2x7+3x7²):162=7⁴x162:162=7⁴=2401

3)
a) b=4¹⁵:(2¹⁰)³=2³⁰:2³⁰=1⇒D
b) a=2⁵-5²-7⁰=32-25-1=6⇒A

4) 
a)=(3⁴)⁷:3²⁵=3²⁸:3²⁵=3³=27
b)=(2²)¹²:2²²-(2³)⁹:2²⁶=2²⁴:2²²-2²⁷:2²⁶=2²-2=4-2=2
c)=(5⁴x5⁴)³:5²²-2⁴=(5⁸)³:5²²-16=5²⁴:5²²-16=5²-16=25-16=9

Succes !
