Put it on the calc on this site,

it shows $\mathtt{\dfrac{6}{100}\times 16,824 = 1009.44}$

I am going to use another way to solve this equation.

aftenn provided a good start, Substitute x = ln a.......

$\dfrac{e^x+3}{4e^{-x}+5}=2\\ e^x+3=\dfrac{8}{e^x}+10\\ e^{\ln a}+3=\dfrac{8}{e^{\ln a}}+10\\ a+3 = \dfrac{8}{a}+10\\ a= \dfrac{8}{a}+7\\ a^2-7a-8=0\\ (a+1)(a-8)=0\\ (e^x+1)(e^x-8)=0\\\text{Set each factor to 0}\\ e^x=-1 \text{ have no real solutions}\\\text{PS: }x=\pi i \text{ is a solution but it's not real}\\ e^x=8\\ x = \ln 8$

If you want imaginary solutions too x = pi(i) or x = ln 8

$18+ \dfrac{6}3(2^2+5)\\ = 18 + 2(9)\\ = 36$

Same as Kaleb's answer.(Kaleb? Sanders? Sorry I come from Hong Kong)

232 m = 16 x 87

m = 16 x 87 / 232 = 6

isn't this expanded? (-3)^0 = 1

5 into expanded form is 5

1 into expanded form is 1.

Anything except zero to the zero power is 1.

Hey :D
