What is 9 times 52 using mental math property

1 answer:

3 0

Everyone works differently in mental meth.

To calculate 9*52, we note that 9=10-1, so mentally calculate
9(52)
=(10-1)(52)
=520-52 [ subtract 20 from each number]
=(520-20)-(52-20)
=500-32
=468.

Alternatively,
9*52=9*50+9*2=450+18=468

If you're good with multiplication and division,
9*52=3*3(52)=3*156=450+18=468

Prime factorization of 25

Dafna11 [192]

The prime factorization of 25 is simple. Just find the square root. (If you know what it is.) Since 5*5 equals 25, and 5 is prime that means the prime factorization of 25 is 5*5.
