Solve : [{(12-4)-:2}+16]-:5

Simplify 12-8-:2-{16of(-2)+(3xx5-4)}

12^16xx12^-4 =

5 19/16- 3 2/5

Find the equation of the plane passing through the line (x-8)/3=(y+19)/-16=(z-10)/7 and the point (1,2,-4) .

{(1/3)^(-3)-(1/2)^(-3)}-:(1/4)^(-3) = (a) (19)/(64) (b) (64)/(19) (c) (27)/(16) (d) (-19)/(64)

{(1/3)^(-3)-(1/2)^(-3)}-:(1/4)^(-3) = (19)/(64) (b) (64)/(19) (27)/(16) (d) (-19)/(64)

The value of charge on the oil droplets experimentally observed were -1.6 xx 10^(-19), - 2.4 xx 10^(-19) and - 4xx10^(-19) C. The value of electronic charge, indicated by these results is (1) -1.6 xx 10^(-19) (2) -2.4 xx 10^(-19) (3) -4 xx 10^(-19) (4) - 0.8 xx 10^(-19)
