Answer: -48

Step-by-step explanation: You will add the 4 to each side of the equation, making the 4 on the left side cancel and on the right side when you add The 4, you are actually subtracting because anytime you have a negative and a positive you will subtract and take the sign of the larger number. That will leave you with x/3=-16. Multiply everything by 3 to get rid of the fraction and that will leave you with x=-48

Given that 2^x = 7, find the value of 4^x-1.

Helga [31]

$4=2^2\\\\4^x=(2^2)^x=(2^x)^2=7^2=49\\\\4^x-1=49-1=48$

$If\ is\ 4^{x-1},\ then\\\\4^{x-1}=\dfrac{4^x}{4}=\dfrac{49}{4}=12\frac{1}{4}$

$Used:\\\dfrac{a^n}{a^m}=a^{n-m}$
