Replace ∗ with a monomial so that the expression can be rewritten as a square of a sum or a difference:

0.01b2+ ∗ + 100c2

The star * can be replaced by 2bc

Step-by-step explanation:

Square Of A Binomial

The expression can be expanded as . Equivalently, if we have the expansion we can reduce to the power of 2. If we know a term is the square of a monomial, we can find the original term by taking the square root.

The given expression is

It's supposed to be the square of a binomial, so we need to test if both of the given terms are perfect squares

Once we are sure we have both square terms, we can complete the expression with the remaining part of the expansion, i.e. twice the first by the second term. In other words

The full expression will be

which can be reduced to

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2
