Exponential equation
Not what you're looking for?
Solve the following for x: 4(2^x)=56
in the order of operations Pemdas requires that exponentation takes precedence over multiplication, so we cannot multiply 4*2 without first evaluating 2^x, but we could divide both sides by 4. Also remember x is an exponent and we have to take logarithmic of both sides to bring the exponent down. Please help me with this. Thank you.
