This  is not multiply anon, it is divide.

And,

You cannot divide by 0    

It is fantastic that you are back zegroes.  We have all missed you.  

$$\\4/5 * 10^9/10^7\\
=0.8 * 10^2\\
=80$$

TRY GOOGLING IT      

a=50

t=8.4

u=0

find s

formula [2] has these variables and no others so that is the one you need to use

$$\\s=ut+\frac{1}{2}at^2\\
\\s=0+\frac{1}{2}*50*8.4^2\\$$

YOU CAN FINISH IT   

If you invest $700 in a bond that pays 6% yearly interest rate compounded quarterly, how much total money will you have after 8 years?

$$\\FV= 700(1+0.06/4)^{(8*4)}\\\\
FV= 700(1+0.015)^{32}\\\\
FV= 700(1.015)^{32}\\\\$$

You can finish it.    :)

this is a future value of an ordinary solution question.

C=5000

i=0.1

n=40

You can do the math.  

$$\\(\pi+3+\pi+3+4)/2-\pi\\\\
=(2\pi+10)/2-pi\\\\
=\pi+5-pi\\\\
=5$$

691437877426050 ÷ The cube root of 1 ÷ 16

=691437877426050 ÷ 1 ÷ 16

=691437877426050  ÷ 16

Now use the calc on the home page.
