1/8 = 1/10 + 1/50 + 1/200 = 0.125
\(\quad y(5x^2+2x)-x(2y-6y^2)\\ =5x^2y+2xy-2xy+6xy^2\\ =5x^2y+6xy^2\)
\(\dfrac{\sqrt3}{\sqrt{15}}\\ =\dfrac{\sqrt3}{\sqrt3\times\sqrt5}\\ =\dfrac{1}{\sqrt5}\\ =\dfrac{\sqrt5}{5}\)
f(x) = 2x + 2(-x) = 2x - 2x = 0.
\(+5-(-9)+(+3)\\ =5 + 9 + 3\\ = 17\)
Number = 100C7 = 16007560800. :)
Use the calculator on this site!! The calculator is really useful!!
\(7\left(\left(18-6\right)-6\right)\\ = 7(12-6)\\ = 7(6)\\ =42\)
magnitude of cU
= c (magnitude of U)
= -3(\(\sqrt{5^2+(-12)^2}\))
= -3(13)
= -39.
Use the format of a/b for \(\dfrac{a}{b}\)
