MONG CÁC BẠN GIÚP ĐỠ . CÁC BẠN LÀM NHANH GIÚP MÌNH NHA . CẢM ƠN CÁC BẠN TRƯỚC NHA MÌNH CẦN GẤP LẮM
\(\frac{5,4:0,4\times1420+4,5\times780\times3}{3+6+9+12+15+18+21+24+27}\)
\(=\frac{13,5\times1420+13,5\times780}{\left(3+27\right)+\left(6+24\right)+\left(9+21\right)+\left(12+18\right)+15}\)
\(=\frac{13,5\times\left(1420+780\right)}{30+30+30+30+15}\)
\(=\frac{13,5\times2200}{135}\)
\(=\frac{29700}{135}\)
\(=220\)
Tính:a) \(\frac{4^6\times9^5+6^9\times120}{8^4\times3^{12}-6^{11}}\)
\(\frac{4^6\times9^5+6^9\times120}{-8^4\times3^{12}-6^{11}}\)help me
\(=\frac{2^{12}\times3^{10}+2^9\times3^9\times2^3\times3\times5}{-2^{12}\times3^{12}-2^{11}\times3^{11}}\)
\(=\frac{2^{12}\times3^{10}+2^{12}\times3^{10}\times5}{-2^{11}\times3^{11}\times\left(2\times3+1\right)}\)
\(=\frac{2^{12}\times3^{10}\times\left(1+5\right)}{-2^{11}\times3^{11}\times7}\)
\(=\frac{2^{13}\times3^{11}}{-2^{11}\times3^{11}\times7}\)
\(=\frac{-4}{7}\)
\(\frac{4^6\times9^5+6^9\times120}{8^4\times3^{12}-6^{11}}\)
tính \(\frac{4^6\times9^5+120\times6^9}{8^4\times3^{12}-6^{11}}\)
Bài làm :
\(\frac{4^6\times9^5+120\times6^9}{8^4\times3^{12}-6^{11}}\)
\(=\frac{\left(2^2\right)^6\times\left(3^2\right)^5+2^3\times5\times3\times\left(2\times3\right)^9}{\left(2^3\right)^4\times3^{12}-\left(2\times3\right)^{11}}\)
\(=\frac{2^{12}\times3^{10}+2^3\times5\times3\times2^9\times3^9}{2^{12}\times3^{12}-2^{11}\times3^{11}}\)
\(=\frac{2^{12}\times3^{10}\times\left(1+5\right)}{2^{11}\times3^{11}\times\left(2\times3-1\right)}\)
\(=\frac{2\times6}{3\times5}\)
\(=\frac{4}{5}\)
Học tốt nhé
thực hiện phép tính:\(A=\frac{2^{12}\times4^6\times9^2}{2^{12}\times3^6+8^4\times3^5}-\frac{5^{10}\times7^3-25^2\times49^2}{125^3\times7^3+5^9\times14^3}\)
Tính:
\(\frac{2^{12}\times3^5-4^6\times9^2}{12^6+8^4\times3^5}-\frac{5^{10}\times7^3-25^5\times49^2}{\left(125\times7\right)^3+5^9\times14^3}\)
Số cây cam là:
120 : ( 2 + 3 ) x 2 = 48 (cây)
Số cây xoài là:
( 1 + 5 ) = 20 ( cây )
Số cây chanh là:
120 - ( 48 + 20 ) = 52 ( cây )
Đáp số : cam : 48 cây
xoài : 20 cây
chanh : 52 cây.
