Write the number
19 ones
5 tens
3 hundreds

369

Step-by-step explanation:

Think about place value. You will align the last number of each number to its place value given and fill in the spaces left with zeroes.

                                              HUNDREDS           TENS              ONES

19 ones = 19                                0                            1                        9

5 tens = 50                                 0                            5                       0

3 hundreds = 300                      3                            0                       0

Then to get the number, all you need to do is add them up together:

300 + 50 + 19 = 369

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
