For q1 and q2 I have given explanation already.
q3 to multiply radicals the index must be same.
option a . different index. ∛5 √2
option b . same index so √3 √2 = √6
option c. again different index.
Answer:
90.3
Step-by-step explanation:
.6×.85=.51
.2×1.00=.2
.1×.97=.097
.1×.96=.096
weight in %, times, grade in %
then add them up
.51 + .2 + .097 + .096 = .903
.903=90.3%
N would be equal to -1, so the last pair of parentheses would be (6,-1).
