987 7 raised to the power of 8 raised to the power of 9. This equals7.0316765e+60 !!
The unit digit of 3127173 is the unit digit of 7173. The other digits of 3127 are multiples of 10 and so they cannot contribute to the unit digit. Now the unit digits of the powers of 7 are Power -- Unit digit 0 -- 1 1 -- 7 2 -- 9 3 -- 3 4 -- 1 and you are back into the loop (of 1-7-9-3). So, you only need consider 7 to the power 173 modulo 4. That is, the remainder when 173 is divided by 4. 173 = 1 mod 4 So the unit digit of 3127173 is the same as the unit digit of 7173 which is the unit digit of 71 which is 7.
9 and 4, respectively; the number will end in 49.
49 = 7 x 7

6.004 x 107 = 6.004 x 10,000,000 = 60,040,000 Alternatively, in multiplying by a power of 10, move the decimal point the power number of digits right (positive) or left (negative), inserting zeros if you run out of digits: 6.004 x 107 the power of 10 is 7, so move decimal point 7 digits right after 3 moves run out of digits, so insert 4 zeros → 60,040,000. Multiplying by a negative power of 10 is the same as dividing by the positive power of 10, eg x 10-3 is the same as ÷ 103.
