Question

compute two decimal places of decimal by use of binomial formula 1.(0.98)^6

Answer 1

Answer: 0.88

Step-by-step explanation:

• To calculate $(0.98)^{6}$using binomial formulae.

• We can write it as $(1-0.02)^{6}$

• So,$(x-y)^{6}=x^{6}-6x^{5}y+15x^{4}y^{2}-20x^{3}y^{3}+15x^{2} y^{4}-6xy^{5}+y^{6}$
• Now putting x=1 and y=0.02 in the formulae.
• $(1-0.02)^{6}$=0.88.
• Hence,the result is 0.88.
