Which expression is equivalent to 9^3/3^3

Allisa [31]

Answer:

3^3

Step-by-step explanation:

Exponents

9^3 can be rewritten as

3^2 ^3

Using exponent rules a^b^c = a^ (b*c)

3^2^3 = 3^6

3^6 / 3^3

We know that a^b / a^c = a^(b-c)

3^6 / 3^3 = 3^(6-3) = 3^3

Evaluate log 2 base 8

iren2701 [21]

Answer: The correct answer is: " 3 " .

_______________________________

Step-by-step explanation:

_______________________________

The problem given is:

_______________________________

Evaluate: log 2 base 8 .

_______________________________

Rewrite as: " $log_2}8 = ? _______________$ " ; $log_2}8 = ? _______________$

_______________________

Take note of the following definition of a logarithm:

_______________________

" $log_{m}n = a$ " ; ↔ " $m^{a} =n$ " ;

_______________________

in which: $m$ refers to the "base" ;

$n$ refers to the "argument" ;

$a$ refers to the "exponent" ;

______________________________

As such:

" $log_2}8 = ? _______________$ "

⇔ " $2^{x} = 8$ " ; Solve for "x" ;

_______________

Note:

2⁰ = 1 ;

2¹ = 2 ;

2² = 2 * 2 = 4 ;

2³ = 2 * 2 * 2 = 8 .

___________________

→ " $2^{x} = 8$ " ;

→ " $2^{3} = 8$ " ; since: " $2^{3} = 2 *2 *2 = 8$ " ;

→ as such: " x = 3 " ;

______________________

Thus:

"log 2 base 8 " ;

= $log{_{2}}8 = 3$ .

Hope this helps!

Best wishes to you!

A store has clearance items that have been marked down by 35%. They are having a sale, advertising an additional 45% off clearan

wariber [46]

Your answer is 35.75%.

Let’s pretend something at the store is $100. (It will save some math later)

100 - 35% leaves 65% (0.65 as a decimal)
100 x 0.65 = 65
That’s the price after the first discount. If we take 45% off of the sale price, we’ll be left with 55%, 0.55

65 x 0.55 = $35.75

Now normally you’d compare 35.75(sale price)/ 100(original price) to % off (x)/100, but doe this example, it’s unnecessary.

35.75/100 = x%/100

P varies directly with T and p=10 when T=500. When T=509, find T

Zepler [3.9K]

Answer:

Let,

P= kT

P = 10, when T = 500

So, 10=k500

or, k=10/500

or, k=1/50

When T=509

P=kT

or, P=(1/50)×509

or, P=508/50

or, P = 10.18

And when P = 509 (since the question isn't clear)

509=(1/50)×T

or, T=509×50

or, T=25450
