Simplify (b^9)^3
A.b^24
B.b^6
C.b^27
D.b^9

Answers

Answer:

C. b^27

Step-by-step explanation:

By the definition of exponents

$(b^9)^3=b^9*b^9*b^9$

And since for any real numbers $r,x,$ and $y$

$r^x*r^y=r^((x+y))$

This makes

$(b^9)^3=b^9*b^9*b^9=b^{{9+9+9}}=\boxed{b^(27)}$

Which is choice C.

Alternatively, we could use the identity

$(r^x)^y=r^(xy)$

in which case

$(b^9)^3=b^((9*3))= \boxed{b^(27)}$

which is the same answer.

the school can only seat 50 students in every bus. If the school is planning on taking 360 students on a field trip. How many busses do they need. (show work) with independent variable dependent variable constant term and coefficient

Answers

so you would do 360/50
simplified you would get 36/5 this simplifies to about 7 and 1/5

so you would need 7 and 1/5 bus or 7.2 bus
but you can't have 1/5 buss so you would need to make the 1/5 into a 1 so
7+1=8
8 busses neede

50x = 360
x is the number of buses
x = 360/50 => 36/5
x = 7.2

Independent Variable: x
Dependent Variable: 360 (or y)
Coefficient: 50 (b/c of 50x)
I don't see a constant term, sorry
