(245) x (215) = 260
4.5
45 * 2 = 90
15 and -3
you could do 45 multiplied by 2 and nine multiplied by 2 so your answer should be 18/90
The result is 90
4.5
The factor pairs of 45 are: 1 × 45 3 × 15 5 × 9
45 * 2 = 90
1 x 45, 3 x 15, 5 x 9
15 and -3
you could do 45 multiplied by 2 and nine multiplied by 2 so your answer should be 18/90
These pairs of numbers, when multiplied, equal 90: (1, 90) (2, 45) (3, 30) (5, 18) (6, 15) (9, 10)
2/5 x 45 = 18
If something is "to the power of 15" then it means it is multiplied by itself 14 times (one less than 15 as the original number is already to the power of 1).An example:So 2 to the power of 15, which we write as 215 = 2 * 2 * 2 * 2 etc... (so we have 15 written 2's in total meaning we will make 14 multiplications) is equal to 32,768.
The result is 90
Factors of 90: 1, 90 2, 45 3, 30 5, 18 6, 15 9, 10
1 and 90, 2 and 45, 3 and 30, 5 and 18, 6 and 15... and finally 9 and 10
