Answer 1

5)
a)13la1
b)23la4
c)2la15:2la10=2la5
d)11la5-11la5=0
e)3la6x5la3:(3la6x5la3)=1
f)(2la2)la12:2la23+(3la2)la15:3la29=2la24:2la23+3la30:3la29=2+3=5
g)3la206:(3la2)la103=3la206:3la206=1
1)
a=2la2=4=C
b=12=A
c=3la4=81=F
d=36=6la2=B
e=5la15=D
f=4la3-2la6=(2la2)la3-2la6=2la6-2la6=0=E

Answer 2

5) a)13⁶÷13⁵=13⁶⁻⁵=13
b)23⁷÷23²÷23=23⁷⁻²⁻¹=23⁴
c)(2³)⁵÷2¹⁰=2³ˣ⁵⁻¹⁰=2⁵
d)11⁵⁰÷11⁴⁵-11⁵=11⁵⁰⁻⁴⁵-11⁵=11⁵-11⁵=0
e)(3²x5)³÷(3⁶x5³)=(3⁶x5³)÷(3⁶x5³)=1
f)4¹²÷2²³+9¹⁵÷3²⁹=(2²)¹²÷2²³+(3²)¹⁵÷3²⁹=2²⁴⁻²³+3³⁰⁻²⁹=2+3=5
g)(3x3²x3³x3²⁰⁰)÷9¹⁰³=3¹⁺²⁺³⁺²⁰⁰÷(3²)¹⁰³=3²⁰⁶÷3²⁰⁶=1

1)a-C
b-A

e-D
f-E

2)a) 4²⁵÷4²³-3²³÷3²¹=4²⁵⁻²³-3²³⁻²¹=4²-3²=16-9=7
b) (14-11)²⁵÷(23-20)²⁵=3²⁵÷3²⁵=1
c) (3³)⁸÷(3⁶x3⁴)=3³ˣ⁸÷3⁶⁺⁴=3²⁴÷3¹⁰=3²⁴⁻¹⁰=3¹⁴
d) 24³÷6³-4²³÷4²⁰=(24÷6)³-4²³⁻²⁰=4³-4³=0
e) 5¹⁷⁶x5⁰x5²⁴÷5¹⁹⁹=1x5¹⁷⁶⁺²⁴-¹⁹⁹=5
f)2²⁴x3²⁴-6²⁴=(2x3)²⁴-6²⁴=6²⁴-6²⁴
g) (5⁷+5⁸+5⁹)÷5⁶=5⁷(1+5+25)÷5⁶=5⁷⁻⁶ˣ31=5x31=155
