Answer:
78
Step-by-step explanation:
5^2 = 25 5^3 = 125 them two added together equals 150
6^2 = 36 so 36 plus 36 equals 72
150-72=78
3 × 100 = 300
the easiest way to do it is just add the same amount of zero's to the number you multiplied with. for example
3 × 10000 if you would just take out the zero's
it would look like this. 3 × 1
the answer of course would be 3 then you can put the zero's back in the answer (30000)
at least that's how I understood it
3 × 100 =
3 × 1(00) =
-->
-->
(00)
3 × 1(00) = 3
3 × 100 = 300
The answers are A, C and D
