Question

Simplify and write in exponential form with negative exponent: (i) 2 −1 ( 5 3 ) 4 + ( 3 5 ) −2 ÷ 17 9 (ii) (−7) 3 × ( 1 −7 ) −9 ÷ (−7) 10 plzz answer plzz plzz plzz plzz plzz

Answer 1

Answer:

(i):- 2-1(53)4+(35)-2÷179

= 1 × 212-70÷179

= 212 -70 ÷ 179

= 142÷179

= 0.793296089 ans.

(ii):- (-7)3×(1-7)-9÷(-7)10

= -21 × (-6)-9 ÷ -70

= -21× 54 ÷ -70

= -1134 ÷ -70

= 16.2 ans.
