What is the simplified value of the exponential expression 27}? оооо 3 9 1/3 1/9

iVinArrow [24]

Note: Your exponential expression seems a little unclear. Because 27 is not an exponential expression.

But, I am assuming that your exponential expression is:

$\:27^{\frac{1}{3}}$

The reason is that my solution would still clear your concept about this topic, no matter what the question is.

Answer:

The simplified value of the exponential expression is:

$27^{\frac{1}{3}}=3$

Step-by-step explanation:

Assuming the exponential expression

$\:27^{\frac{1}{3}}$

$\mathrm{Factor\:the\:number:\:}\:27=3^3$

$=\left(3^3\right)^{\frac{1}{3}}$

$\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0$

$\left(3^3\right)^{\frac{1}{3}}=3^{3\cdot \frac{1}{3}}$

$=3^{3\cdot \frac{1}{3}}$

$=3^1$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a$

$=3$

Therefore, the simplified value of the exponential expression is:

$27^{\frac{1}{3}}=3$

8. A cellphone company charges $29.99 per month for the first 500 minutes of calls and $0.30 a minute for any calls over the 500

scZoUnD [109]

Answer:

C) $64.49

Step-by-step explanation:

let 'x' = #minutes

cost = 29.99 + 0.3(x-500)

= 29.99 + .3(115)

= 29.99 + 34.50

= $64.49
