4^5 (the caret means raised to the power of)
4 X 4 X 4 x 4 X 4 = 4^5 So the exponent is 5.
You multiply the base number by itself as many times as the exponent tells you. Example 4^4 =4•4•4•4= 256

The expression 4x4x4x4x4 can be written in index notation as 4^5, where the base is 4 and the exponent is 5. When you raise a number to an exponent, it means multiplying the base by itself the number of times indicated by the exponent. Therefore, 4^5 is equal to 1024.
4 is the base, 2 is the exponent.
An exponent is 1; 16 = 16^1
It is: 21a exponent 6
4x4x4=base 4 with the exponent 3 or 64
120
You multiply the base number by itself as many times as the exponent tells you. Example 4^4 =4•4•4•4= 256
You are multiplying 4 three times so 4^3
10 power of 4
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?
In the expression 18 to the 4th power, the exponent is 4. An exponent indicates the number of times the base number (in this case, 18) is multiplied by itself. So, 18 to the 4th power means 18 multiplied by itself 4 times, which is equal to 104,976.
11(base number) was multiplied by it's own number five times, in exponent form that would be eleven to the power of 5 ex: 11x11x11x11x11=11to the power of 5
One way to view the exponent, especially when it is a natural number, is how many times something need to be multiplied by itself. So 4^5 has exponent 5 and base 4 and it means 4 multiplied by itself 5 times, ie 4x4x4x4x4 We can then extent this to negative integers and to an exponent of zero and then to rational exponents. More on that if you want to know.
x2y4z6-121 Use the difference of two squares to factorise:- (xy2z3-11)(xy2z3+11)
Do you mean: 2-4 if so then it is 1/16.
