What is the question??
Step-by-step explanation:
4^x=2×2^x=2×7=14
4^x-1=14-1=13
Answer:
V=904.32 cubic centimeters
Step-by-step explanation:
V=4/3(Pi)x6^3
1.4375
<u>Step-by-step explanation:</u>
Step 1:
Let the given equation be 
To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.
Step 2:
Let us expand the equation as 
Step 3:
Let us expand it further as 
Step 4:
To find X segregate X in one side and all other remaining terms in other side as follows

After the simplification the numerical value is

Step 5:
Keep X along one side and bring 48 to the denominator of another side to find X as follows

And the value of X is 1.4375
By graphing the given options as shown in attached figure
<span>f(x) = (1/4)^x+2 ⇒⇒⇒⇒ The black graph
f(x) = (1/4)^x +2 </span><span>⇒⇒⇒⇒ The red graph
