Question

Excluding trailing zeroes, how many digits does 0.4^24 x 0.375^22 have to the right of the decimal point? Please explain.

Answer 1

42

Explanation:

Answer 2

42 digits does
`0.4^(24) * 0.375^(22)` have to the right of the decimal point.

Explanation:

Trailing zeroes states that those which you get in decimal representation and after that there comes no digit.

Given the expression:

`0.4^(24) * 0.375^(22)`

Simplify:

`1.19709242282867431640625 * 10^(-19)`

Now, you will operate
`10^(-19)`

Which means decimal point will be shifted 19 digits left of its present position.

we have then,

`0.000000000000000000119709242282867431640625`

Hence, 42 digits does
`0.4^(24) * 0.375^(22)` have to the right of the decimal point.
