-2/3-1/3(2X-1)=-5
BAN NAO GIAI HO MINH VOI
cos giai ho mink bai nau ko |x-5=|-3x+2|
b,|x-5|+|X^2-25|=0
c, |2x-3|+|2x+4|=7
Tìm GTLN hoặc GTNN
a,h(x)=3.|x-2|+5
b,1/(x^2-2x+2)
Mink cần gấp lắm! Giúp mink nha
ban nao onl thay bai nay lam on giai ho mk voi nha!!!!!!!
Tim x :
\(5^x+1-5^x=500\)
Tinh P giup minh voi : P = 1+1/2(1+2)+1/3(1+2+3)+1/4(1+2+3+4)+...+1/16(1+2+3+...+16) . Ban nao lam duoc thi giup minh nha . Minh se tick ung ho .
ho minh nha
\(\frac{7^{x+1}+7^{x+2}+7^x}{57}=\frac{5^{2x}+5^{2x+1}+5^{2x+3}}{131}\)
tim 3 chữ số x ;y ; z biết rằng
\(\frac{x}{2}\)=\(\frac{y}{3}\) ;;; \(\frac{y}{4}\)= \(\frac{z}{5}\) và x + y -z = 10
giai hộ mink nha
ai lam dung mink tk cho
ban nao onl thay bai nay lam on giai giup mk voi nha!!!!!
tinh :
\(\frac{2^{50}.3^{61}+2^{90}.3^{16}}{2^{51}.3^{61}+2^{31}.3^{16}}\)
ban nao onl thay bai nay lam on giai gium mk voi nha!!!!!!!
