4 is the base, 2 is the exponent.
6.213*105
An exponent is 1; 16 = 16^1
An exponent tells how many times the base is used as a factor. 10^3 = 10 x 10 x 10
You multiply the base number by itself as many times as the exponent tells you. Example 4^4 =4•4•4•4= 256
10 with an exponent of -6 = 4
You evaluate the powers of 10 and a exponent of positive 4.
The mantissa is multiplied by 10 raised to the power as shown by the exponent. So, if the exponent is 4, then you multiply the mantissa by 10^4 = 10,000. If the exponent is -4 then you multiply the mantissa by 10^(-4) = 0.0001 or, equivalently, divide by 10^4.
For 104 the base is 10 and the exponent is 4.
10 power of 4
It is 2.5/(10*10*10*10) or 2.5*0.0001
