value of $6^{-3}$ is $\frac{1}{216}$

Step-by-step explanation:

Given the expression:

$6^{-3}$

Using the rule:

$a^{-n} = \frac{1}{a^n}$

$6^{-3}$

Apply on this expression we have;

$\frac{1}{6^3}$

we can write 6^3 as:

$6^3=6 \cdot 6 \cdot 6$

then;

$\frac{1}{6 \cdot 6 \cdot 6}$

Simplify:

$\frac{1}{216}$

Therefore, the value of $6^{-3}$ is $\frac{1}{216}$

Bananas cost: $0.25
Apples cost: $0.30

4b+5a=2.50
10b+3a=3.40
You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have

12b+15a=7.50
50b+15a=17
Subtract them and end up with

-38b=-9.5
solve: b=0.25, substitute b in any equation and get a=0.30
Hope this helped
