The power of -2.3 of 10 is between -2 and -3, the order of magnitude is between -5 and -6, and the order of magnitude is -6.
Let x = 6 54 be the logarithm lgx = lg6 54 = 54lg6, lg6=0.778 15 12504, 54lg6=42.020 1675, that is, lgx = 42.02438.
The zeroth power of a number
The zeroth power of any nonzero number is equal to 1.
Usually stands for cubic.
The third power of 5 is 125, that is, 5×5×5= 125.
The quadratic of 5 is 25, that is, 5×5=25.
The 1 power of 5 is 5, that is, 5× 1=5.
It can be seen that when n≥0, the power of (n+ 1) of 5 needs to be divided by a 5, so the power of 0 of 5 can be defined as 55 =1.
