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.
Hello and thank you for posting your question to Brainmass.
set 2^x =y
4y = 56
This shows how to solve an equation using exponents and logarithms.
