Verified answer

(x − 7)^3/2 = 64

=> (x − 7)^3/2 = 16^3/2

=> x - 7 = 16

=> x = 16 + 7

=> x = 23 Ans.

Raise everything to the power 2/3:

x-7=64^{2/3}

x-7=16

x=23

what on earth is (x - 7) 3/2 ?

Is it :-

(x - 7)^(3/2) = 64

x - 7 = 16

x = 23

3x - 21 = 2*64 = 128

3x = 128 + 21 = 149

x = 49 2/3

Nick. Have a little heart and confidence in yourself; We will do this togather.

(X-7)3/2= 64; 3X/2 - 21/2=64 3x?2=21/2 + 64=10.5 + 64 =74.5 . No we are going to multiply both sides by 2/3 t0 get (2/3)(3X/2=(2/3) x (74.5) Note: you see the fractions on the left cancel each other out to leave us with just. Gotta go now; however, just multiply 74.5 by 2 and divide your result by 3 to find X. Good Luck.

seems it relatively is on its final legs. Taking 20-30 seconds to load and it sucks! think of i will pass play someplace else for some and notice if it relatively is extra appropriate when I come lower back. i presumed it replaced into merely my puter for the reason that its slow besides, yet that's no longer the case I see.
