B=C*[13*37*(5*3-15)]=0
\(A=\dfrac{2^{10}\cdot78}{2^8\cdot26\cdot4}=\dfrac{78}{26}=3\)
a, A = \(\dfrac{3^{10}\times10+3^{10}\times6}{3^9\times2^4}\)
A = \(\dfrac{3^{10}\times\left(10+6\right)}{3^9\times2^4}\)
A = \(\dfrac{3^{10}\times16}{3^9\times16}\)
A = 3
c, C = \(\dfrac{36^{10}\times25^{15}}{30^8}\)
C = \(\dfrac{\left(6^2\right)^{10}.\left(5^2\right)^{15}}{30^8}\)
C = \(\dfrac{6^{20}.5^{30}}{6^8.5^8}\)
C = 612.522
\(A=2\left(\dfrac{1}{2\cdot3}+\dfrac{1}{3\cdot4}+...+\dfrac{1}{98\cdot99}\right)\)
\(=2\left(\dfrac{1}{2}-\dfrac{1}{3}+\dfrac{1}{3}-\dfrac{1}{4}+...+\dfrac{1}{98}-\dfrac{1}{99}\right)\)
\(=2\cdot\dfrac{97}{198}=\dfrac{97}{99}\)
a) \(2^3\cdot2^4\cdot2^5\cdot2^6\cdot2^7\cdot2^8\cdot2^9\cdot2^{10}\)
\(=2^{3+4+5+6+7+8+9+10}\)
\(=2^{52}\)
b) \(3^2\cdot3^3\cdot3^4\cdot3^5\)
\(=3^{2+3+4+5}\)
\(=3^{14}\)
c) \(4^2\cdot4^3\cdot4^4\)
\(=4^{2+3+4}\)
\(=4^9\)
d) \(5^2\cdot5^3\cdot5^4\)
\(=5^{2+3+4}\)
\(=5^9\)
mik cũng hỏi giống bạn nè
