Question

One hectare is equal to 10000 Sq. M. How much will this be in sq. cm? Express the answer in scientific notation ​

Answer 1

Answer:

10^4 sq. m in sq cm = 10^4* 10^4 sq cm

Step-by-step explanation:

thus answer is 10^8 sq com

above we used law of surds:-

accordingly if we have two numbers having same base but different powers and bases are being multiplied then we add the powers of the both bases

like say 2^7* 2^8

here we have both 2 as bases and both 2 are being multiplied

so

1. Since bases are common(both are 2)

therefore

2. powers will be added

so 2^7*2^8 = 2^ (7+8)

= 2^15

and for sq m to sq cm

we used this:-

We know 1 metre = 100 cm (1)

so squre both sides

we get 1 sq metre= 10000 sq cm (2)

so for 10000 sq M

we multiply 10000 to equation two by both sides

:- 10000 sq m = 100000000 sq cm or 10^8 sq cm since it has 8 zeros.

That is sufficient for you to even understand concepts

rather than mugging up the answers.
