tìm x biết
a/ x2 . (x+2)+4(x+2)=0
b/ 3x+2 +4.3x+1 +3x-1 = 66
Tìm giá trị của x biết rằng:
a) 4.3×X+(-1.3)×X+1.6=8.2
b) -5.6 ×X + 16.2 = 3.4×X

Rút gọn biểu thức: B=\(\frac{4^6.9^5+6^9.120}{8^4.3^{12}+6^{11}}\)
Tính:
A=\(\dfrac{4^2.25^2+32.125}{2^3.5^2}\)
B=\(\dfrac{4^6.9^5+6^4.120}{8^4.3^{12}-6^{11}}\)
Tính :
A=\(\dfrac{4^2.25^2+32.125}{2^3.5^2}\)
B=\(\dfrac{4^6.9^5+6^4.120}{8^4.3^{12}-6^{11}}\)
2. Rút gọn:
A=\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\)
B=\(\frac{4^6.9^5.6^9.120}{8^4.3^{12}+6^{11}}\)
