What will come in the place of question (?) mark in following the question:

$({16}^2+{30}^2)-?=1000$

To find the value that should replace the question mark (?), we can set up the given mathematical equation and solve it step-by-step.

The given equation is:

$({16}^2+{30}^2)-?=1000$

First, we calculate the squares of the numbers inside the parentheses:

${16}^2=16\times 16=256$

${30}^2=30\times 30=900$

Now, substitute these squared values back into the equation:

$(256+900)-?=1000$

Add the numbers inside the parentheses:

$256+900=1156$

The equation simplifies to:

$1156-?=1000$

To solve for the question mark (?), rearrange the terms:

$?=1156-1000$

$?=156$

Thus, the correct answer is 156.
