Why would you use power notation?
Powers are a convenient shortcut for repeated multiplication.
Use repeated multiplication to show exponent of 77?
7×7× 7×7×7×7×7
Can you raise a number to a power on a 4 function calculator?
If the power is a positive integer, you can use repeated multiplication. For example: 34 = 3 x 3 x 3 x 3
Program to find the sum of the series as 1 plus x plus x2 plus x3 plus?
The idea is to use a loop. To reduce the additional effort (and innacuracy) of power calculations, you can do repeated multiplication, as part of the loop. For example, in Java:double sum = 1;double xpower = 1.0;for (int i = 1; i
How do you know that a multiplication fact is correct?
There are a few ways to determine if a multiplication fact is correct:Repeated addition: since multiplication is simply repeated addition at its base, you can reaffirm a multiplication fact by repeatedly adding the number you're multiplying. With the basic multiplication facts (i.e. times tables), this is possibly the best option.Division: Since it's simply the reverse of multiplication, then you can just reverse the process to confirm it.Using multiple methods: There are multiple ways to do multiplication than just the usual long multiplication done in school, such as lattice multiplication, and Ayurvedic multiplication (just to name the two I know). You can use these to confirm a multiplication.
