Answer:
Where is the function shown below?
Step-by-step explanation:
(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84
Answer:
1. 
2. 
3. 
Step-by-step explanation:

Write in exponential form
Using the law of logarithm which says if
then

By comparison;
A = 16; b = 2 and x = 4
The expression
becomes


Write in exponential form
Applying the same law as used in (1) above;
A = 2; b = 16 and 
The expression
becomes

Write in logarithm form
Using the law of logarithm which says if
then

By comparison;
b = 2; x = z and A = y
The expression
becomes
