Quick Please :) Exponents and powers
MrRissso [65]

Step-by-step explanation:

(  {4}^{ - 3} ) ^{ - 3}  =  {4}^{9}

( { - 4}^{9} )  ^{2} = ( - 4) {}^{18}

( {4}^{6} ) ^{ - 3}  =      \frac{1}{{4}^{18}}

(  { - 4}^{9} ) {}^{2}  = ( { - 4})^{18}

({4}^{0} ) =  {4}^{0}

Hope this is correct and helpful

5+2x=2x+6 please answer
madam [21]

If we firstly consider only the terms in x.

subtract 2x from both sides of the equation

⇒5+2x

−2x=2x−2x

+6

Observe that the x terms are eliminated and we are left with

5+0=0+6 that is 5=6 which is invalid

There is no solution to this equation.

4(2x - 5) + 15 = 11 Write the steps you will use to solve the equation and explain each step.
vagabundo [1.1K]
First, multiply 4*2x-4*-5= 8x-20.
Second, add 15 to 8x-20
Third, that would equal 8x-20+15=11 
Fourth, 15+-20= -5 
Fifth, 8x-5=11
Sixth, add +5 to -5 and +5 to 11= 8x=16 
Last, do 8x/8x and 16/8x 
The answer is x=2
