x^2*23y^2 = 1.78x10^32*z
x^2 = (1.78x10^32 z)/(23y^2)
x^2 = 7.739x10^30 z/y^2
x = 2.782x10^15 √z/y
Ok. I'll take it as written
(1.3*10^-4 x) = (4.7/x) - 6.3*10^-3
1.3*10^-4 x^2 = 4.7 - 6.3*10^-3 x
0.00013x^2 + 0.0063x - 4.7 = 0
x = -215.91, 167.45
I see you're still using x for both a variable and multiplication
Find x
1) x^2*23y^2 = 1.78x10^32*z
2) 1.3*10^-4 x=4.7/x -6.3*10^-3
Please help
