Help someone how do you solve this

Flauer [41]

Answer:

a = 10/3

Step-by-step explanation:

This can be written as:

$x^{2} (x^{4})^{1/3} = x^{a}$

Anything to the power of 1/3 means to find the cube root. We can simplify this to:

$x^{2} (x^{4/3}) = x^{a}$

I just multiplied 4 and 1/3 (because of the second index law $(a^{m})^{n} = a^{mn}$ ). Now, we can add the powers because the bases are the same and we are multiplying (first index law):

$x^{10/3} = x^{a}$

a = 10/3

Hope this helps!

Let x² + 15x = 49 . What values make an equivalent number sentence after completing the square? Enter your answers in the box

Pavlova-9 [17]

Answer:

Step-by-step explanation:

15/2 = 7.5 and (7.5)^2 = 56.25 so

x^2 + 15x + 56.25 = 49 + 56.25

x^2 + 15x + 56.25 = 105.25.

Determine the sum of the arithmetic series: 5+18 +31 +44 + ... 161.

Finger [1]

Answer:

1079

Step-by-step explanation:

Hello,

18-5 = 13

31-18=13

44-31=13

161=5+13*12

So we need to compute

$\displaystyle \sum_{k=0}^{k=12} \ {(5+13k)}\\\\=\sum_{k=0}^{k=12} \ {(5)} + 13\sum_{k=1}^{k=12} \ {(k)}\\\\=13*5+13*\dfrac{12*13}{2}\\\\=65+13*13*6\\\\=65+1014\\\\=1079$

Thanks
