c ) 36 x ( 28 + 82 ) + 64 x ( 69 + 41 ) = 36 x 110 + 64 x 110 = ( 36 + 64 ) x 110 = 100 x 110 = 11000

Mik nhanh nhất đấy , nhớ click cho mik nha !!!!!!!!!!!!!!!!!!!
a) 5 x 25 x 216 x 4
= ( 5 x 216 ) x ( 25 x 4 )
= 1080 x 100
= 108000
b) 4 x 37 x 25 x 16
= ( 4 x 25 ) x ( 37 x 16 )
= 100 x 592
= 59200
10.(17 - x) - 64 = 36
<=> 10.(17 - x) = 100
<=> 17 - x = 10
<=> x = 7
@Van Dong Pham
\(10\left(17-x\right)-64=36\)
\(10\left(17-x\right)=36+64\)
\(10\left(17-x\right)=100\)
\(17-x=100:10\)
\(17-x=10\)
\(x=17-10\)
\(x=7\left(tm\right)\)
Vậy ...............
10(17 - x) - 64 = 36
<=> 10(17 - x) = 100
<=> 17 - x = 10
<=> x = 7

chúc bạn học tốt , tick cho mk nhé

a,,83+17x=100
\(\Rightarrow\)17x=100-83
\(\Rightarrow17x=17\)
\(\Rightarrow\)x=1
Vậy x=1
b,100-64:(x-1)=36
\(\Rightarrow\)64:(x-1)=100-36
\(\Rightarrow\)64:(x-1)=64
\(\Rightarrow\)x-1=1
\(\Rightarrow\)x=2
Vậy x=2
a, ( 46 + 54 ) + 17 = 100 + 17 = 117
b, ( 4 . 25 ) . 37 = 100 . 37 = 3700
c, 87 . ( 36 + 64 ) = 87 . 100 = 8700
a,46+17+54
=(46+54)+17
=100+17
=117
b,4.37.25
=(4.25).37
=100.37
=3700
c,87.36+87.64
=87.(36+64)
=87.100
=8700
Chúc bạn học giỏi nha ^-^
\(A=\left(4^2\right)^{17}.\frac{64^{36}}{8^{35}.32^{34}}\)
\(A=16^{17}.\frac{64^{2.36}}{\left(2^3\right)^{35}.\left(2^5\right)^{34}}\)
\(A=...6.\frac{...6^{36}}{2^{105}.2^{170}}\)
17 . 64 + 36 . 17 = ?
= 17 . ( 64 + 36 )
= 17 . 100
= 1700
Chúc bạn học tốt !
