27 to the power of 3x=81

Mathematics
1 answer:
hoa [83]3 years ago

Answer:

x=4/9

Step-by-step explanation:

27 ^(3x) = 81

Replace 27 with 3^3    and 81 with 3^4

3^3^(3x) = 3^4

We know that a^b^c = a^(b*c)

3^(9x) = 3^4

Since the bases are the same, the exponents are the same

9x =4

Divide each side by 9

9x/9 = 4/9

x = 4/9

Mark earns $135 for selling a $1,500 refrigerator. Which sale listed has the same commission rate? A) $36 commission on a $400 d
sdas [7]
So the percentage Mark makes comparative to the price of the refrigerator sold is \frac{135}{1500}=0.09= 9%. If we take 9% of the given sale prices:
A: 0.09*400=36
B: 0.09*500=45
C: 0.09*1400=126
D: 0.09*600=54

So (A) has the same commission rate.

In the two questions, we first replace the division with multiplication with flipping the fraction after the division sign, secondly we analyze any equation that needs analysis to simplify it, thirdly, to simplify the fraction by deleting the numerator and the similar denominator .
