Question

.00001=1/10 3x+2

anonymous · Answer

Is that $$.00001=\frac{1}{10} (3x+2)$$?

anonymous · Answer

i think it might be an exponent

anonymous · Answer

1/10 ^ 3x+2

anonymous · Answer

$$.00001=\frac{1}{10}^{3x+2}$$$$.00001=\frac{1^{3x+2}}{10^{3x+2}}$$$$.00001=\frac{1}{10^{3x+2}}$$$$0=\frac{100000}{10^{3x+2}}$$$$10^{3x+2}=100000$$$$10^{3x+2}=10^5$$ So $$3x+2=5$$$$3x=3$$$$x=1$$

.00001 = (1 / 10)^(3x +2) 

Multiply and divide by 100000 on left hand side

1/100000 = 1/10^(3x+2)

   100000 = 10^(3x + 2)

          10^5 = 10^(3x +2)

here base values are equal, so equate the exponents 

               5   = 3x +2 
              -2           -2
          ------------------
               3  =  3x

divide by 3 on both sides

               3/3 = 3x/3

                1 = x
