HEYA......
(102)^2
= (100 + 2)^2
= (100)^2 + (2)^2 + 2×100×2
= 10000 + 4 + 400
= 10404
(102)^2
= (100 + 2)^2
= (100)^2 + (2)^2 + 2×100×2
= 10000 + 4 + 400
= 10404
chakulee:
and
in the right angled LMN, angle M is equal to 90 degree .if 1 (LM) is equal to 12cm and 1 (LN) is equal to 20 cm find the length of seg MN
Use pythagorean theorem to find out the answer..
As we know it is a right angled triangle,
LM square + MN square = LN square
12 square + MN square = 20 square
144 + MN square = 400
MN square = 256
MN = 16
yeah...

We know a formula,
( a + b )² = a² + b² + 2ab
Now let's make use of this formula to find out the value of (102)² without actual multiplication.
As, 102 = 100 + 2,
(100 + 2)² = 100² + 2² + 2 (100) (2)
= 10000 + 4 + 400
= 10404
∴ (102)² = 10404.
Hope my answer helps you..
