Simplify the expression 4 to the 5th power times 4 to the 3rd power?
(45) x (43) = 48
Why is 5 to the second power read as 5 squared?
5 to the second power is read as 5 squared because it is 52 or 5 times 5 or 25. We call a square number for ex: 4 (2 times 2), 16 (4 times 4), et cetera. 8 is not a square number being that none of its factors are a number times itself.
What is 4 to the 3rd multiplied by 4 to the fifth power?
4 to the third power multiplied by 4 to the 5th power can be written as (4^3)x(4^5) When a number is raised to a power, it means that that number is multiplied by itself as many times as the power denotes. For example, 2 cubed, or 2^3, is two multiplied by itself three times. 2^3=2x2x2=8 In this case, (4^3)x(4^5)=(4x4x4)x(4x4x4x4x4) As you can see, this is the same as multiplying 4 by itself 8 times, or 4^8. At this point, the only way to know the answer is to multiply 4 by itself 8 times. 4x4x4x4x4x4x4x4=65,536 65,536 is your answer.
What is the answer to multiply the sum of 5 and 4 by 8?
