Calculation root sign (LG ^ 25-2lg5 + 1)

The original formula = √ (lg5-1) & sup2;
=|lg5-1|
=|1-lg5|
=|lg10-lg5|
=|lg10/5|
=|lg2|
=lg2

Calculation: (5 + 1) (52 + 1) (54 + 1) (58 + 1) (516 + 1) + 14=______ ．

（5+1）（52+1）（54+1）（58+1）（516+1）+14，=14（5-1）（5+1）（52+1）（54+1）（58+1）（516+1）+14，=14（532-1）+14，=5324．

After the driver makes an emergency brake in this section, the inspector measures that the length of the brake trace is 12m. If the dynamic friction coefficient between the tire and the road is 0.6, ask the driver whether he has violated the speed limit specified in this section of the road. (hint: calculate the acceleration when braking from the braking friction, and then calculate the initial speed from the kinematic formula.)
