a: =5-78*32

=5-2496

=-2491

b: \(=6\left(9-6\right)=6\cdot3=18\)

c: \(=46\cdot\dfrac{\left(123-42\right)}{81}=46\)

d: \(=181+3-84+8\cdot25\)

=100+200

=300

e: \(=64\cdot35+140\cdot84-1=2240-1+11760\)

=14000-1

=13999

f: \(=3^3+25\cdot8-1=26+200=226\)

g: \(=3+2^4+1=16+4=20\)

h: \(=36:4\cdot3+2\cdot25-1=27+50-1=27+49=76\)

:)?

giúp e với em cần gấp ạ

\(A=3^2\cdot4^3-3^2+333\)

\(=3^2\cdot63+333\)

\(=3^2\cdot\left(63+37\right)\)

\(=30^2\)

\(B=5\cdot3^2+4\cdot3^2=3^2\cdot9=9^2\)

d: Ta có: \(D=5^3+6^3+59\)

\(=125+216+59\)

\(=400=20^2\)

Ông ơi

thằng  trung anh ơiiiiiiiiiiiii

ta có

2^4.3=2^12

2^3.3=2^9

vì 2^12<2^9 nên 2^4.3<2^3.3

Giải: (^ là mũ)

a) 3^8 : 3^4 + 2^2 . 2^3

= 6561 : 81 + 4 . 8

= 81 + 32

= 113

Mấy câu sau bn làm tương tự nhé!

b: \(=2^{12}\cdot3^4\cdot\dfrac{3^{10}}{3^{12}\cdot2^{12}}=3^2=9\)

c: \(=\dfrac{7^2\cdot3^2\cdot7\cdot2\cdot5^3}{5^3\cdot7^3\cdot2\cdot3}=\dfrac{3^2}{3}=3\)

d: \(=\dfrac{5^3\cdot3^6\cdot5^4\cdot2^8\cdot3^{16}\cdot2^2}{\left(2^2\cdot3^2\cdot5\right)^5}=\dfrac{5^{10}\cdot3^{22}\cdot2^{10}}{2^{10}\cdot3^{10}\cdot5^5}=3^{12}\cdot5^5\)

a) Ta có : 3⁴ . 3⁵ = 3^{4 + 5} = 3⁹

b) Ta có : 5⁵ . 5⁷ = 5^{5 +7} = 5¹²

c) Ta có : 9². 27³ = (3²)² = (3³)³ = 3^2.2 . 3^3.3 = 3⁴. 3⁹ = 3^{4+ 9} = 3¹³

d) Ta có : 8³ . 16⁴ = (2³)³ . (2⁴)⁴ = 2^3.3 . 2^4.4 = 2⁹ . 2¹⁶ = 2²⁵

Chúc bạn học tốt

a)\(3^4.3^5=3^4-^5=3^9\)

b)\(5^5.5^7=5^5+^7=5^{12}\)

c)\(9^2.27^3=\left(3^2\right)^2=\left(3^3\right)^2=3^2^2:3^9=3^4+9=3^{13}\)

d)\(8^3.16^4=\left(2^3\right)^3.2^4=2^{3.3}.2.44=2^9.2^{16}=2^{15}\)

~Study well~ :)

thank you
