Tính hợp lí :
1) \(\frac{4^9.36+64^4}{16^4.100}\)
2) \(\frac{2^{13}+2^5}{2^{10}+2^2}\)
3) \(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
4) \(\frac{21^2.14.125}{35^5.6}\)
1: \(=\dfrac{2^{20}\cdot3^2+2^{24}}{2^{16}\cdot2^2\cdot5^2}=\dfrac{2^{20}\left(3^2+2^4\right)}{2^{18}\cdot5^2}=4\)
2: \(=\dfrac{2^5\left(2^8+1\right)}{2^2\left(2^8+1\right)}=2^3=8\)
3: \(=\dfrac{11\cdot3^{29}-3^{30}}{2^2\cdot3^{28}}=\dfrac{3^{29}\cdot8}{2^2\cdot3^{28}}=2\cdot3=6\)
A=4^9.36+64^4/16^4.100
A=4^9.36+64^4/16^4.100
A= 262144.36+256.100
A=9437184+25600
A=9462784
\(A=\frac{4^9.36+64^4}{16^4.100}=\frac{2^{20}.\left(9+16\right)}{2^{18}.5^2}=\frac{2^{20}.5^2}{2^{18}.5^2}=2^2=4\)
C = \(\dfrac{4^9.36+64^4}{16^4.100}\)
\(C=\dfrac{4^9.36+64^4}{16^4.100}=\dfrac{4^9.36+4^{12}}{4^9.25}=\dfrac{4^9\left(36+4^3\right)}{4^9.25}=\dfrac{100}{25}=4\)
=2^18.36+2^24/2^16.100
=2^18.(36+2^6)/2^16.100
=2^4.100/100

giúp mk với mk cần gấp:
bài1:tính giá trị biểu thức:
a) A= 2^10.13+2^10.65/2^8.104
b) B= 4^9.36+64^4/16^4.100

g) G= 45^3.20^4.18^2/180^5
h) H= 11.3^22.3^7-9^15/(2.3^14)^2
1. tính giá trị biểu thức :
a, A= 4^9.36+64^4 phần 16^4.100
b, B= 4^6.3^4.9^5 phần 6^12
c, C= 21^2.14.12^5 phần 35^5 .6
d, D= 45^3. 20^4.18^2 phần 180^5
giải giúp mk nha
tính giá trị của biểu thức
C=4^9.36+64^4 / 16^4.100
D=4^6.3^4.9^5 / 16^12
4^9.36+64^4/16^4.100
4^6.3^4.9^5/6^12
ai tl đúg mk tick cho nha
B = 4^9.36+64^4
16^4.100
B = 2^20.(9+16)
2^18.5^2
B = 2^20.5^2
2^18.5^2
B = 2^2
B = 4
D = 4^6.3^4.9^5
6^12
D = 2^12.3^4.9^5
2^12.3^12
D = 2^12.3^14
2^12.3^12
D = 3^2
D = 9
\(\frac{4^9.36+64^4}{16^4.100}=\frac{4^{10}\left(9+8\right)}{4^{10}.25}=\frac{17}{25}\)
