PLEASEE ANSWER ALL THESE I NEED IT LIKE RIGHT NOW 1) 5^0 =1
2) (-4)^0 = 1
3) (1/3)^0 = 1
4) 3^-3 = 1/3^3 = 1/(3 x 3 x 3) =1/27
5) (-2) ^-5 1/2^5 = 1/32
6) (10^5)(10^6) = 10^11
7) (1/4)^8 (1/4)^-5
8) (-6)^2 (-6)^0 = -6^2
9) 0^0 = undefined, cannot evaluate
10) 0^-1 = 1/0^1 = undefined
11) 4^2/4^3
12) 5^3/5^6
13) (2/3)^-4
14) 9^-8 9^-2

only 10/60 isn't equivalent

hope this : )

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
