Answer:
B and C
Step-by-step explanation:
[tex]300 \times {2}^{10x} = 2700 \\ {2}^{10x} = \frac{2700}{300} = \frac{27}{3} = 9 \\ {2}^{10x} = 9 \\ log( {2}^{10x} ) = log(9) \\ 10x \times log(2) = log(9) \\ (10 log(2) )x = log(9) \\ x = \frac{ log(9) }{10 \times log(2) } [/tex]
However, if you replace log with ln you can easily reach to the following solution as well.
[tex]x = \frac{ ln(9) }{10 \times ln(2) } [/tex]
