WebAboutTranscript. The Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand expressions like this directly. But with the Binomial theorem, the process is relatively fast! Created … WebThe power of a starts from n and decreases till it becomes 0. The binomial coefficients of the terms equidistant from the beginning and the end are equal. For Example, in (a + b) …

WebApr 10, 2024 · As can be seen, here, 101 can also be written as the sum or the difference of two numbers, in a way that the binomial theorem can be used. Thus, 101 = 100+1 Hence, (101) 4 = (100+1) 4 Now, after the binomial theorem is applied, we get: (101) 4 = (100+1) 4 = 4 C 0 (100) 4 + 4 C 1 (100) 3 (1) + 4 C 2 (100) 2 (1) 2 + 4 C 3 (100) (1) 3 + 4 C 4 (1) 4 WebBinomial theorem formula class 11 is useful in the expansion of any power of a binomial in the form of a series.
