Which of the following correctly simplifies the expression 2 to the power of 3 multiplied by 3 to the power of 0 whole over 5, t

o-na [289]

9514 1404 393

Answer:

(a) 64/25

Step-by-step explanation:

The relevant properties of exponents are ...

a^0 = 1 . . . . a ≠ 0

(a^b)^c = a^(bc)

(ab)^c = (a^c)(b^c)

Your expression simplifies to ...

$\left(\dfrac{2^3\cdot3^0}{5}\right)^2=\dfrac{2^{3\cdot2}\cdot1^2}{5^2}=\dfrac{2^6}{5^2}=\boxed{\dfrac{64}{25}}$

Wht is -3(2x-1)+8=15

Svetllana [295]

Answer:

x=- $\frac{2}{3}$

Step-by-step explanation:

subtract -3(2x-1)+8=15

-8 -8

_____________

-3(2x-1)=7

divide

$\frac{-3(2x-1)}{-3} =\frac{7}{3}$

then simplify

2x-1= $\frac{7}{3}$

add both sides

2x-1+1= $\frac{7}{3}$ +1

simplify again

2x-1+1= $\frac{7}{3}$ +1=2x= $-\frac{4}{3}$

divide by 2

2x= $-\frac{4}{3}$

-2 -2

_________

2x÷2=1

$-\frac{4}{6}divided by 2$

x=- $\frac{2}{3}$
