5 to the 12 power.
a to the b power means b lots of a, all multiplied together. Thus 5 to the 5 power or 55 is 5x5x5x5x5, and 5 to the 3 power, or 53 is 5x5x5. Thus the question can be written as 5x5x5x5x5x4x5x5x5x6. This is now a simple calculation that comes out at 9,375,000. Thus 5 to the 5 power times 4 times 5 to the 3 power times 6 is 9,375,000.
GCF is 60
5 to the 7th power
It is correct only for the first one. The second one should be 3 to the power 2 times 2 times 5.
5 times by 10 to the power of 3 in standard notation = 5,000
It is: 25
5 to the power of 8.
8 x 9 x 5 and 4 x 3 x 25 360 and 300 The GCF is 60.
