\(2^8:2^2+3^3:3^3\)

=64+1

=65

\(2^8:2^2+3^3:3^3\)

= \(2^{8-2}+3^{3-3}\)

= \(2^6+3^0\)

= 64 + 1

= 65

cho mình hỏi 3 mũ 3 chia 3 bằng bao nhiêu

\(B=5.3^2+4.3^2=3^2\left(5+4\right)=9.9=9^2\)

\(C=5^3+6^3+59=125+216+59=400=20^2\)

\(D=5.4^3+2^4.5+41=320+80+41=441=21^2\)

b: \(5\cdot3^2+4\cdot3^2=3^2\cdot9=3^4\)

c: \(5^3+6^3+59=20^2\)

\(5\cdot4^3+2^4\cdot5+41=21^2\)

a^5:aa^3=a^5-3=a^2

\(a^5:a^3=a^{5-3}=a^2\)

~ hok tốt ~

=a⁵:a³=a^5-3=a²

\(3^{2-\left(77-2.11+7^2\right)}=3^{2-77+22-49}=3^{-102}\)

3^{2 -} ( 77 - 2 )¹¹ + 7²

Kết quả 1: - 422351360321044921817

Kết quả 2: ~ - 4,22351360321044 x 10²⁰

giúp e đg cần gấp ạa

\(a^2.a^3.a^7.b^2.b\)

\(=a^{2+3+7}.b^{2+1}\)

\(=a^{12}.b^3\)

\(a^2.a^3.a^7.b^2.b=\left(a^2.a^3.a^7\right)\left(b^2.b\right)=\left(a^{2+3+7}\right)\left(b^{2+1}\right)=a^{12}.b^3\)

2^3/2^4=1/2=0,5

=1/2

olm duyệt đi

\(\frac{2^3}{2^4}=\frac{2^3}{2^3\cdot2}=\frac{1}{1\cdot2}=\frac{1}{2}\)

7^2 x 3 - 5^2 x 3

= 3 x ( 7^2 - 5^2 )

= 3 x ( 49 - 25 )

7². 3 - 5² . 3

= 49.3 - 25.3

= 3.(49 - 25)

= 3.24

= 72
