Simplify:1(27)-1/3+1(625)-1/4.
Simplify the given expression by writing in exponent form:
We know that 33=27,54=625
127-1/3+1625-1/4=133-1/3+154-1/4=13-1+15-1
Usinga-1=1a we have:
13-1+15-1=3+5=8
Hence , the value of 127-1/3+1625-1/4=8
Determine whether the following numbers are in proportion or not:
13,14,16,17
loge(n+1)−loge(n−1)=4a[(1n)+(13n3)+(15n5)+...∞] Find 8a.
