Question

Solve for x, rounding to the nearest hundredth.
70 - 2^3x = 35

Answer 1

x= 1.71

Explanation:

We need to isolate x in the equation, first subtract 70 from the left side, so the equation is, -
`2^(3x\\)`=-35. There is a negative sign in both equations so we cancel them out so our equation is
`2^(3x\\)`=35. Now we use log, so our equation now looks like {log(35)/log(2)}/3=x. When we do it out we get that x=1.70976, and when rounded we get, x-1.71.

Answer 2

x=4.375
