How to measure the power in mathematics?
Chemical order of magnitude, such as how to calculate the negative 5.6 power of 10, whether the order of magnitude is positive or -6 power of 10.

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.
