Question

please answer the above equation

Answer 1

when year given in rational
it need to change into a real number
so we need to change
now year multiply by 2 and rate divide by 2

=40,000(1+5/100)^3/2
now,3/2×2 and 5/2
year= 3 and rate =2.5%

=40,000(1+2.5/100)^3
=40,000(1+1/40)^3
=40,000×(41/40)^3
=40,000×41/40×41/40×41/40
$\frac{10 \times 41 \times 41 \times 41 }{16}$
=689210/16
=43075.62
