Question

11. Use algebraic methods to find the following 305^2​

Answer 1

Step-by-step explanation:

Step by step ,

Here we have (305)^2

And 305 can be written as 300 + 5

means, 305=300+5

And if square both side means,

(305)^2 = (300+5)^2.

we know that {a+b}^2=a^2 + b^2 + 2ab

we just have to put the value as a=300

and b=5,

(300+5)^2= 300^2+5^2+2(300)(5)

we just have to solve the equation

90,000+25+3000 CHECK BY YOURSELF

We get the answer 93,025

Hence 305^2=93,025.
