\(\dfrac{1}{8}=12.5\%\)
So \(8\dfrac{3}{8}=8+\dfrac{1}{8}\times 3=800\% + 12.5\%\times 3=837.5\%\)
Yes. Definitely there is some trick.
Remember that \(i^2=-1\),
so \(i^4=i^2\cdot i^2=-1\cdot -1=1\)
Therefore \(i^{4n}=(i^4)^n=1^n=1\), for any integer n.
\(i^8=(i^4)^2=1^2=1\)
\(i^{25}=i^{24}\times i=(i^4)^6\times i=1\times i = i\)
\(\cos^{-1}\) this one?
it is same as "acos".
\(v=\dfrac{1}{4}\pi d^2z\\ 4v= \pi d^2z\\ d^2=\dfrac{4v}{\pi z}\)
\(\because x^3=20x+7y\text{ and }y^3=7x+20y\\ \therefore x^3-y^3=(x-y)(x^2+xy+y^2)=13x-13y\\ x^2+xy+y^2 = 13\\ x^3+y^3 =(x+y)(x^2-xy+y^2)=27(x+y)\\ x^2-xy+y^2=27\\ (x^2+xy+y^2)-(x^2-xy+y^2)=-14\\ xy = -7\)

Dividing by a number means multiplying the reciprocal of the number.
So 1/2 divided by 7 = 1/2 x 1/7 = 1/(2x7) = 1/14
Because △ABC is similar to △DEF, angle ABC should equal 60 deg as well.
\(\boxed{ \text{The sum of all interior angles of a triangle is 180}^{\circ}}\)
So Angle C = 180 - 55 - 60 = 65 deg :D
Do you mean 125 in cubed instead?
Then side length = \(\sqrt[3]{125}\) which is 5 in.
