Which applies the power of a power rule to simplify the expression (8 Superscript 12 Baseline) cubed?

(8^{12})^3=8^{12\times 3}=8^{36}

Step-by-step explanation:

Given :  the expression (8^{12})^3

We have to simplify the given  expression and choose the correct from the given options.

Consider the expression (8^{12})^3

Using property of exponents,

\left(a^b\right)^c=a^{b\times c}

We have,

(8^{12})^3=8^{12\times 3}=8^{36}

72 is the answer to this problem

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
