Answer:
= (- 475)
Step-by-step explanation:
Given:
(-5) × (-5) × ... × (-5) = (-5)95
Find:
Sign of the product
Computation:
(-5) × (-5) × ... × (-5) = (-5)95
= (- 475)
No, it is not compulsory to do all calculation to find sigh of product
Negative number × odd time = Negative number
Negative number × even time = Positive number number
Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
