Answer:
4 or 5 or even 6
Step-by-step explanation:
Log base b=logb
4 log₂ 2x+ 2logb x=4
log₂(2x)⁴+logb x²=log₂16
log₂ 16x⁴+ logb x²=log₂ 16
logb x²=log₂ 16 - log₂ 16x⁴
logb x²=log₂ (16/16x⁴)
logb x²= log₂ x⁻⁴
logb x²=log₂ x² / log₂ b
log₂ x² / log₂ b=-log x⁴
log₂ b=log₂ x² /- log₂ x⁴
log₂ b=2 log x / -4 log₂ x
log₂ b=-1/2 ⇔ b=2⁻¹/² =1/√2=(√2)/2≈ 0.707106781....
Answer: b=(√2)/2
To chek
if x=10
log base √2/2= log√2/2
4 log₂ 20 + 2log√2/2 10=4(4.321928095...)+2 (-6.64385619=
= 17.28771238-13.28771238=4
We just use the techniques in algebra. Isolate the terms that are not x on the right side, while only the x variable on the left side. To do this, divide both sides by b. The b on the left side would then cancel out. As a result, the equation for x is written below:
x = -7/b
This question doesnt make sense u need to attach a picture
Add all the numbers and divide by how many there are.
The mean is 38.9
