Question

(a^4n.a^ 3n×a^2n)^2
​

Answer 1

Answer:

Subtracting a fraction from a whole

Rewrite the whole as a fraction using t2 as the denominator :

t t • t2

t = — = ——————

1 t2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator.

Answer 2

Step-by-step explanation:

(a cos theeta - b sin theeta )= c ,prove that (a sin theeta + b cos theeta) =

$\sqrt{ {a}^{2} + {b}^{2} - {c}^{2} }$
