Answer:

Step-by-step explanation:

Given that,

x^8/x^a=x²

Applying indices

Division rule a^m ÷ a^n = a^(m-n)

Then,

x^8/x^a=x²

x^(8-a)=x²

For this to be equal means that, the power are equals since they have the same base

Then, 8-a=2

8+2=a

So, a=10

Taking the second equation

(x^6)^b=x¹²

Using indices again

x^(6b)=x¹²

Also, for this to be equal

6b=12

Then, b=12/6

b=2

Then, b=2 and =10

We need to find b-a.

b-a=2-10=-8

Then, the answer to b-a is -8

Answer:

Hey there! ok , so your equation would be 28 / 3

Step-by-step explanation:

The equation would be 28/3 because there are 28 students in the class and the ratio of boys to girls is 3-9 meaning that it is 1/3, which is the same as dividing by 3, so the equation would be 28/3

It’s not 0.615 , or 0.75 or the one shown in the picture

Dafna1 [17]

$2.40714$

1) Let's evaluate that expression, given that a=4.9, b=-7, and c=-0.5

$\begin{gathered} a^3\div b^2+c^3 \\ (4.9)^3\div(-7)^2+(-0.5)^3= \\ \frac{4.9^3}{\left(-7\right)^2+\left(-0.5\right)^3} \\ \\ \frac{4.9^3}{48.875} \\ \\ \frac{117.649}{48.875} \\ \\ 2.40714 \end{gathered}$

Note that we have rewritten it as a fraction so that we can easily operate. Also, we have applied here the PEMDAS order of operations, prioritizing the exponents.
