Using radicals , write an equivalent expression for the expression 2 1/3

liq [111]

I'm assuming that the 1/3 is an exponent.

If so, then $2^{1/3} = \sqrt[3]{2}$

Which is the cube root of 2. Raising any value to the 1/3 power is the same as taking the cube root.

Log8(216)+[log(42)_log(6)]÷log(49)

makkiz [27]

Answer:

3 log (3) + 1/2

Step-by-step explanation:

log8(216) + [log(42) - log(6)] ÷ log(49) =
log (216)/ log (8) + [log (7) + log (6) - log (6)] ÷ 2 log (7) =
3 log (3) log (2) / 3 log (2) + log (7) / 2 log (7) =
3 log (3) + 1/2

If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?

8_murik_8 [283]

Answer: option B

Step-by-step explanation:

The circumference of a circle can be calculated with this formula:

$C=2\pi r$

Where "C" is the circumference of the circle and "r" is the radius of the circle.

The area of a circle can be calculated with:

$A=\pi r^2$

Where "r" is the radius.

Knowing the area, you can solve for the radius:

$r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm$

Substituting into $C=2\pi r$ , you get that the circumference of this circle is:

$C=2\pi (3cm)=6\pi\ cm$
