(4/24)2/3 = 82/3 = (81/3)2 = [3√(8)]2 = [2]2 = 4
hmm.. 6th grade? Review? That's what I have…working on it right now haha sooo… #1 a. is 15≠3x7 b. is x+5>75 c. is 9+13/9≤14 #2 a. 200÷(4*5)=10 b. 16+2to the second power -(5+3)=12 #3 a. 5*6+8*2=76 b. 20-8÷2 to the 2nd power=18
3x + 6y = 48 .... Eq.1-5x + 6y = 32 .... Eq.2 .... in another way 6y = 5x + 32Put the value of Eq.2 in Eq. 13x + 5x + 32 = 488x = 48 - 328x = 16x = 16/8 ...... X = 2To find the value of Y put the value of X in Eq.26y = 5x + 326y = 5(2) + 326y = 10 + 326y = 42y = 42/6 ...... Y + 7
