Answer:4) 1. (3^4)^3=3^12 ,
2.(-10^3)^6=-10^18 others are similar...
5) 1. (2^7/2^5)=2^2,4 ,
2.(a^7/a^3)=a^4 ,
7. [(-4)^3 x (-4)^5)]/[ (-4)^2 x(-4)^3]=4^3 others are similar...
Step-by-step explanation: 4)1. step1. 3^(4x3) , 2. step1. -10^(3x6)
step2. 3^12 , step2. -10^18
5)1. step1. 2^(7-5) , 2. step1. a^(7-3)
step2. 2^(2) , step2. a^(4)
7. step1. -4^(3+5)/-4^(2+3)
step2. -4^(8)/-4^(5)
step3. 4^(8-5)
step4. 4^(3)

Answer:
1. add 1/2x to both sides
a. you want to combine the like terms. in this case, it is the x variable.
you are left with 7/6x = 5
2. multiply by 6/7
a. the reciprocal of 7/6 will cancel out the values
