\left \{ {{7x+6\:\:\:\:\:\:x

f(-1)

Solve

-7\cdot \:1+6x                          Swap the negative sign

-7+6x                               Multiply the numbers

-7+6x+7                  Add 7 to both sides

6x                                       Simplify

\frac{6x}{6}                                       Divide both sides by 6

x                                        Simplify

-7\cdot \:1+12x                     Swap the negative sign

-7+12x                          Multiply the numbers

-7+12x+7              Add 7 to both sides

12x                                   Simplify

\frac{12x}{12}                                  Divide both sides by 12

x                                      Simplify

saveliy_v [14]

Answer:

a=5q^ {2}

b=r^{2}s

Step-by-step explanation:

Here 125q^{6} is like the a^{3} in the general formula.

So we can write 125q^{6} as:

(5q^ {2} )^{3}

We can also write r^{6} s^{3} as:

(r^{2}s)^{2}

Therefore:

a³=(5q^ {2} )^{3}

b²=(r^{2}s)^{2}
