Dear Student,

(5) [\frac{3}{7} - 3] 4 = [\frac{3 - 21}{7}] \times 4 = \frac{- 18}{7} \times 4 = \frac{- 72}{7} = - 10.28 (2) 1) 4^{6} \times 4^{- 4} = 4^{[6 + (- 4)]} . . . (a s a^{b} \times a^{c} = a^{b + c}) = 4^{6 - 4} = 4^{2} = 16 N o t e : - w h e n e v e r + i s m u l t i p l i e d b y -, t h e a n s w e r i s i n - F o r r e m a i n i n g q u e s t i o n s, p l e a s e p o s t t h e m i n s e p a r a t e t h e a d f o r r a p i d a s s i s \tan c e .
