What is 5 to the 5 power times 4 times 5 to the 3 power times 6?
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.
How do you solve an exponent?
An exponent means "this many times." So, 4 cubed (to the power of 3; a 3 exponent.) is 4 NOT times 3, but 3 TIMES. So it is 4x4x4(=64). Or, 5 to the power of 5 is 5 times itself 5 times, so, 5x5x5x5x5(=3,125). 3 to the power of 9 is 3 times itself 9 times. Basically, the exponent tells how many times you multiply the number by itself. Does that help?
