\(\frac{\left(5^{2001}-5^{2000}\right)}{5^{2000}}\)
\(=\frac{5^{2000}.\left(5-1\right)}{5^{2000}}\)
\(=4\)
\(\left(7^3+7^5\right).\left(5^4+5^6\right).\left(3^3.3-9^2\right)\)
\(=\left(7^3+7^5\right).\left(5^4+5^6\right).\left(3^4-\left(3^2\right)^2\right)\)
\(=\left(7^3+7^5\right).\left(5^4+5^6\right).\left(3^4-3^4\right)\)
\(=\left(7^3+7^5\right).\left(5^4+5^6\right).0\)
\(=0\)
cảm ơn bạn nhé angle love. kết bạn với mình đi
a) = .\(5^{2001}\):\(5^{2000}\)-\(5^{2000}\):\(5^{2000}\)
=5-1
=4
b)=(\(7^3\)+\(7^5\))x(\(5^4\)+\(5^6\))x(\(9^2\)-\(9^2\))
=0
