156*10-7 = 0.0000156 or as 1.56*10-5 in scientific notation
75 x (1/7)5 1/7 = 7-1 So, (1/7)5 = (7-1)5 = 7-5 Replacing this in the original expression gives, 75 x 7-5 = 7(5 -5) = 70 = 1 Alternatively, (1/7)5 = 15/75 = 1/75 we could then write, 75 x 1/75 = 1
7 to the second power
3(5)5(5)7(7)
(5 × 7) ÷ 5 = 7
7 to the power of 5. This editor will not allow me to show exponents but I hope you understand how to write 7 to the power of 5.

It is the same as 5 to the power of 7 and it equals 78125
7 to the second power
3(5)5(5)7(7)
7 to the third power or 343
(5 × 7) ÷ 5 = 7
It is 5^7 = 78125
You would write 7x7x7x7x7x7 as 7^6 (the ^ means to the power of, 7^6 is the same as 76. You would do this because there are 6 sevens there, and 7^6 means 7 times t times 7 times 7 times 7 times 7.
7 to the power of 3 is: 7 x 7 x 7 = 343 Another way to write it is: 7^3 = 343
4 to the power of 5
