7 times 6 is 42. If you subtract two, you get 42-2= 40.
To find the unit digit of 2 raised to the power of 40, we can observe a pattern. The unit digit of powers of 2 cycles in a pattern: 2, 4, 8, 6. Since 40 is a multiple of 4, the unit digit of 2^40 will be the fourth number in the pattern, which is 6. Thus, the unit digit of 2^40 is 6.
a power of a product is when you are adding the exponents EX: 4 to the 3rd power times 4 to the sixth power -you can just add them so 6 + 3 = 9 Answer: 4 to the ninth power
The product of 4 and 10 is 4x10, which is 40. So the product of 4 and 10 is 40.
10*40 is the first step. Then, 6*0 and add the two products together
