193,400 193,4000 193,400,0 expalin how you decided on the number on the number zeros in products for a, b,c

a) The only factor with zeros is 400, which has 2 of them. Since the least-significant non-zero digits are not 2 or 5, the product 193×4 will not have any trailing zeros. Consequently, the product 193×400 = 77,200 will have 2 zeros.

b) Same reasoning, except with 3 zeros. 193×4000 = 772,000

c) The product of anything and zero is zero. There will be 1 zero in the product 193×400×0 = 0.

If you like, you can factor out the trailing zeros:

... 193×400 = 193×4×100 = (193×4)×100 = 772×100

You can also use scientific notation to keep track of the trailing zeros. Here, the numbers end in 5 and an even number, so result in additional trailing zeros when multiplied.

... 192×500 = 192×5×10² = 960×10² = 96×10¹×10² = 96×10³ = 96000

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
