Question

can anyone explain this to me.
I understood till the blue line drawn.
plz explain the last step, step by step with explanation

Answer 1

Answer:

Explanation:

something raised to 1/2 is the square root of the term and something raised to - means the term goes to the denominator so raised to -1/2 is the square of the term in denominator

example :

$x^{1/2}  = \sqrt{x}$

$x^{-1/2} =\frac{1}{\sqrt{x} }$

Answer 2

Explanation:

you need to put the values alfa=1/2,b=0 and

c=-1/2 in equation (1.3)I.e.

T=k× l power a ×m power b×g power c

i.e.

t=k×l power 1/2 ×m power 0 × g power -1/2

t= k × root L × 1 ×root g (1/2 =root , a power o = 1 )

t=k whole root L /g

hope u understood it!!!

mark me as brainlist !
