what do you mean by that? That isn't a question!

1+2+4+...+64

= 2⁰+2¹+2²+.....+2⁶

Number of terms = 6+1 = 7

$\color{aqua}\frac{950000000}{39500000000}$

= $\color{aqua}\frac{95}{3950}$

= $\color{aqua} \frac{190}{79}$percent

$\color{aqua} \approx 2.41$ percent.

$\color{aqua}log_2(3x-1)=4$

$\color{aqua} 3x-1 = 2^4$

$\color{aqua} 3x=16+1$

$\color{aqua} x= \frac{17}{3}$

$\color{aqua}8-x=2x+8$

$\color{aqua}8=3x+8$

$\color{aqua}3x=0$

$\color{aqua} x=0$

A. other

This is already an expression of y in terms of x. The x isn't in the numerator of the fraction so it's other which is neither linear nor quadratic.

B. quadratic

This is a function and x is to the second power with no fractions, so quadratic.

C. linear

Divide 2 on both sides so it become $y=\frac{2x-1}{8}$ and the x is in the numerator of the fraction so it's linear.

D. other

Divide 3x on both sides, it will become $y=\frac{4}{3x}$ and x isn't in the numerator of the fraction so it's other which is neither linear nor quadratic.

$\sqrt{10}\approx 3$(Corrected to 1 significant figure)

Guest,

2 (-1)^(1/3) and -2 (-1)^(2/3) isn't a real number. So the only real number is -2

1 - 1 = 0

You can't find a square root of the complex number.
